thank you for you videos. i love the references to popular culture in the soviet union.
Just joined up, and I have a question - is it correct that the Nebula Plus content is that which is not on TH-cam?
Neh-bula
@@Althemor yes, it is correct. Nebula Plus videos are exclusive to Nebula only.
Why does Russia issue pilot licenses to people with severe mental retardation? One would think that the last person u would want flying a plane would be someone as stupid as the pilot in this case. Unreal
All air disasters seem terrifying. However, something about going down in a flatspin seems exceedingly miserable.
Being in a spin is (from my experience as a glider student) honestty quite terrifying, and flat spins are mostly unrecoverable on the majority of aircrafts (the harder it is to get in a spin, the harder it is to recover from one). So, while being miserable, there is a point where you know that you will not be able to recover at all.
@@Cassiow106thrust vectoring could help recover from a flat spin right, like motors that can do yaw to try to counteract the spin
@@kyle_mk17yeah nobody is paying for that on passenger aircraft when instead you can just not fly near the flat spin envelope
@@ThePlayerOfGames frfr, also you can just cut throttle on the engine opposite to the flatspin direction (so if it spins left, you cut the right engine) and max power on the remaining engine(s). might work if they are powerful enough, but strictly on military aircraft, theres no chance a big ass passenger recovers from that
@@ThePlayerOfGamesit's like the parachute military aircraft/ test aircraft will be the only one that could justify it
It's interesting that the deadliest air disaster in Soviet history happened in the deadliest moment in world aviation history. The summer of 1985 was the deadliest, with Air India 182, Delta 191, JAL 123, and British Airtours 28M. Aeroflot 5163 slots into this summer, only making it more deadly.
Bad year to be in the skies 😢
Huh thats actually interesting.
AI182 I guess AI182 wasn't mentioned too much in the late eighties but comes up now and again, much to my personal chagrin.
Keep in mind that China Airlines 006 and Iberia 610 happened on the same day (Feb 19 1985), even outside summer wasn't lucky.
1985 ended with Canada's deadliest air crash with Arrow Air 1285.

Two minutes and 33 seconds is a very long time to contemplate every decision you've made in your life that brought you to this moment.
A good quarter of the people were kids who hadn't even made very many decisions at all yet.
@@MGower4465they would have grown up to be orc scum anyway
No worries, their decisions had already been made for them because this was before the dissolution of the USSR.
yeah its not really tho, if you were given a rubix cube with a gun to your head 2.5 minutes will seem like an instant and you wont be thinking about anything other than the cube and the gun..
@@ObiWanCannabi There are tons of stories of people believing they're about to die and thinking about their families and stuff. These people had over 2 minutes to do so and could do nothing to stop their impending death. Whereas if someone has a gun to your head you have the option of fight or flight.
Extreme fatigue is often fatal. And the corruption of the USSR is equally fatal. Having a crew work in extreme heat with no viable shelter to rest is cruel.
The fatigue is definitely what sealed the deal on this one. This is normally an easy to prevent situation in which there are almost always some extenuating circumstances in order for it to happen. It's one of those things that is so simple to prevent.
I've been in that position where I'm so tired that I almost start dreaming before my eyes close all the way. If I'm woken up, I have to fight that fog to clear my mind and focus on what's happening. I can see that happening to the crew, and it's a frightening situation to find one's self in.
I'm only like 10 seconds in, but.......are cockpits not pressurized and climate controlled?

8:11 - Worth noting is that it's nearly impossible to recover any aircraft from a flat spin. This isn't a design weakness or flaw of the TU-154. If you lock up a plane in such a way that it's falling flatly, it's going to be a very bad situation - regardless of make or model.
Only an acrobatic airplane can recover from a flatspin, or at least that's what I've seen, the rule of thumb usually is that the harder it is to enter a spin, the harder it is to recover from it, and as a pilot myself that had to go through spins as part of my training, spins are no joke
Most fighters are able to get out of a flat spin.
@@pr0t0typ38no it greatly depends on any individual aircraft and other conditions and many different aircraft required different steps to exit such flat spins and may need multiple minutes to exit it or even drague chuts on many military aircraft to help the best chances for any aircraft to not be lose to a flat spin is to recover before the aircraft departs flight
Most passenger airliners maybe, but smaller planes like general aviation aircraft, aerobatic aircraft, some gliders, trainers and fighters can generally get out of a flat spin given enough altitude. There's a reason why you need literally thousands of flight hours and years of experience before they even accept you into training to fly passenger airlines. People who get into that line of work the civilian route can only get that experience by working as flight instructors on general aviation aircraft for several years first.
Everyone correcting me is right. Acrobatic aircraft, aircraft with drag chutes, fighters, and small, slow planes and so on are much better off. Airliners could do it, I suppose, if the crew diagnosed the problem correctly almost immediately and had a LOT of altitude to work with. That said, if the crew manages to get the plane into such a predicament to begin with, it seems unlikely that they'd then also be able to correctly identify and respond to the problem. That's not an insult to them, of course; as in the case of this video, convincing your brain that its understanding of reality is wrong is another thing that's almost impossible... especially under high stress.
Ive worked 24, 48, even 96 hours straight as an EMT. Its not safe. We have a system called "safety pauses" where if we feel tired, no matter what, we have to be sent back to our station and left alone for an uninterrupted 2 hour rest. Even still, work culture here pressures us not to use them
USA?
Any logical reason why to employ sleep deprivation on workers?
An all-too-common feature of the Soviet experience was the quiet suffering of individual families who knew only that their family was gone and would never be told how or why. For many decades, Soviet families would lose loved ones in obscure military operations, industrial accidents, and the like, and the most the state would tell them was that their loved one was dead and there might be a body to bury; lucky families might even have an approximate date of death. Many a Soviet graveyard was filled with young men (and some women) who clearly died before their time, but the sum-total of public disclosure on their death was they were dead.
I've never heard about this. Do you have any sources to look further into it?
@@peter_de_Jong817try googling soviet tech disasters. Or better "техногенньіе катастрофьі СССР" and use Google translate
@@peter_de_Jong817 right, is there any truth to this or just the typical Soviet stereotype that everyone parrots?
@@johnrosswilhite9532the thousands who were "safely" outside of the Chernobyl radiation zone set by the Soviet Union are a good place to start, they weren't given the information about the deadly levels of radiation they experienced and the state would never admit it's fault, I'd be surprised if the Russian government currently even acknowledges what their forefathers did then.
The more I watch this channel, the more I learn how true that is.
...a blown fuse. Think about that. A blown fuse with NO redundancy for an instrument was the final nail in the coffin for these people's lives.
For any other country, this was a catastrophe. For the USSR, it was Wednesday.
The fact that the engineers actually bothered to put a fuse there lets you know that it was considered critical equipment by russian standards
@Begeye-bh5ux Soviet Era civil and military aviation were so immersed in their own special category of Hell that even Boeing on its worst day was exponentially better than the Soviets on their best day.
What about the staggering incompetence of the pilots?
@@martijn-velsincompetence?
Just thinking how slow my thinking is when I’m seriously sleep deprived, it’s scary to imagine being awoken in a Soviet cockpit and immediately confronted with a problem that endangers the lives of hundreds of people. Even if the pilots could determine the correct solution to the stall, given their muddled and sluggish thinking, it may still have been too late to save the flight
The current understanding from the US highway advisory board is that driving after being awake for 24 hours is like driving with a BAC of .10. That's bad if true.
@@BiggestCorvid Yup, there's a lot of studies that show the effects of sleep deprivation are very very similar to being impaired/inebriated
I guarantee you, in a life and death situation, even if you're 48 hours without sleep, the adrenaline will make you feel 100% awake again. What's bad is being exhausted while doing something mundane, like driving (or flying). Driving while nodding off is the absolute worst feeling, I carry some powered caffeine in my glove box for when it happens. Probably not healthy but neither is flying off the road into a tree. I know airplanes used to have amphetamines in their survival kits, especially back then, would be a life saver in a situation like that
@@moonasha I don't think drugging our pilots so they can go for longer without sleep is the lesson to be taken from this. You did mention it'd be for an emergency/life saver situation, but we all know this would slowly be pushed from emergency procedure to the norm by certain air companies.
Idk, I've been woken up to life or death situations and my head kicked into gear in a quarter second, flat.
Flew on one of those TU154 once, when we decended in rally hot and humid weather and the cabin filled with dence mist as well as screaming passengers that thought the was a fire..
I refuse to fly on Tupolev aircraft. Luckily, this is not a problem as there are so few flying now.
i refuse to fly on anything Russian. @@MrArgus11111
This is exactly how, at the time I perceived every aeroflot flight, pre Soviet break-up, to be like.
@@MrArgus11111do they really have that bad a reputation? Also, have you ever actually refused to fly on a specific flight because it was a tupolev?
Literally any aircraft though. Was on a flight from Delhi to Dabolim and mist filled the cabin when it has been depressurized.
A blown fuse on a very important warning device? No back up, no dual circuit? A 10 cent fuse FFS.... WOW, just WOW
On boarding a Tu154 our Soviet minder stated, "these are the ones that keep crashing". I have never forgotten that.
So word got out anyway?
At the time of this accident, the Tu-154 had suffered 19 fatal or major accidents in the previous 11 years of service. This included the worst flight accidents in Kazakhstan (Aeroflot Flight 4225, 8 July 1980) and Russian (Aeroflot Flight 3552, 11 October 1984) history. The most recent accident occurred in December 1984. It was not a safe aircraft to fly, and it was operated by an airline with an atrocious safety record.

In a way, it's kind of heartening to know that fashion in the early 80s was just as unflattering to people inside the Iron Curtin as it was to people outside.
I thought that compression stalls and death by flat spins only happened likeable supporting characters in 1980s US Naval Aviation recruitment films.

Love the song. Hate the disaster. The video of the smiling children on their parents’ laps was chilling.
There was a cargo 747 (MK Airlines) crash later on that was somewhat similar. There the direct cause was the crew not using enough power on takeoff (so the plane failed to clear an obstacle and crashed) but they also had been awake much longer than they should've been.
Also the DC-8 that crashed in Guantanamo Bay because the captain banked the plane too much while looking for a beacon that marked Cuban border. They too were overworked with not enough sleep
From Colombia Bogota, thank you for those videos about the USSR, I’m to young to even existed when it fell but learning from their story is very interesting.

Fatigue is the single biggest factor in aviation accidents. Almost every deadly incident involves tired flight crews.
Not true
I would disagree, it probably a factor for a lot of them but, but then being overburdened seems to be just as common. Also poorly designed planes and malfunctions.
Aviation is a highly intricate business after all. It's no surprise that fatigue *is* the single biggest factor in many aviation accidents, when even the lightest forms of fatigue has the potential for pilots and crews to miss a single item on a checklist or procedures they should always be wary of. It's tragic, but in the end it's just human nature. Vigilance is crucial, and every rules and checklists in aviation are written in blood.
I’d imagine every pilot and passenger is always in fatigue mode on every flight. By the time a plane takes off, a typical pilot has already been awake at least for 4 hours. Add to this the nature of flying- extremely dull and drowsy, and every pilot will be in fatigue mode. Fatigue is just something you can attribute to every flight, not just the ones who had an accident, so logically it cannot be the(single) cause of the ones that did, or at least it’s just very hard to prove. Moreover, not sleeping for 24 hours is, in my opinion, unimpactful, it sucks but this is what adults do all the time. I personally went for 72 hours one time without a problem ( playing a video game online)
This air disaster is almost unbearable!! Could it be that darkness played a role? In the daytime, it t would seem the pilots would understand the pitch if the aircraft better because of visual inputs. In the dark over a desert, it had to be completely pitch black!! RIP 😢
Друже, дякую за чудове відео! Гарно рокрита тема "самава вкуснава марожинава из СССР" 👍
You do an amazing job walking through the details of this disaster and also providing interesting social context from the era. I love your channel.
I only have experience in flight sims, but I'm shocked that they kept trying to reduce throttle despite losing more altitude. This seems like a completely avoidable crash.
in my uneducated experience, usually you'd nose down and throttle back up, then climb back to altitude? throttling back while still pulling back on the yolk just seems very counterproductive to me
Hindsight is 2020. Did you guys not watch the video?
“Fatally exhausted”
They must have not been alert to what was going on due to their tiredness.
It probably was avoidable, but being shocked awake while already sleep deprived really messes with your head for a good five minutes afterwards and weird counterintuitive logic can seem completely sound.
It could have been completely avoidable if those pilots had anywhere to sleep before flying 200+ people across the Soviet Union. Every single soul on board was fatally exhausted, but had no other choice but to fly because the airport was lacking in adequate infrastructure.
There is a phenomena in aviation called the Death Spiral, and while it does not fully apply here it is very much a real thing. It usually happens to inexperienced pilots in instrument-only conditions. What happens is, an aircraft will slowly, gradually, enter a turn and start to lose altitude. The pilot at this point has only to ignore what he "thinks" is right and look at the instruments and follow them, and them alone. But what the pilot usually does is yank back on the yoke because _dear God we're losing altitude! More power, more yoke!_ but now the turn becomes sharper. The altimeter starts to unwind. But the plane _can't_ be nearly on its wing! The pilot feels the g-forces pushing him back in the seat! More power, pull back harder! The death spiral is almost inescapable now. The pilot feels himself being pushed deeper into his seat and the last thing they probably think right before they smack into the ground is " _I'm doing everything right, why aren't I going up?!_ " Pilots simply get caught in a fatal decision loop, and each choice they make once they pass a certain point convinces them they're doing the right thing to remedy the situation, and it is in fact making it worse. I've watched F14 crash videos on carriers where the LSO will say in retrospect "If he'd kept his hands off the stick and just put more rudder in he'd have made it", small plane crash investigations where actual death spirals occurred...it's just a simple matter of the pilot's brain, for a few fatal moments, tricking them into thinking they're 100% right and what they're doing is the right action. If they ever realize what's happened, it's usually too late for them and their passengers and/or crew.
Man you are uploading like crazy recently! Make sure you get some sleep
[Video enters flat spin and crashes]
Babe wake up, there's a new paper skies video
Whenever I have to do risk assessment or compliance review, I almost always encounter pushback in the form of "we're not going over the limits, just get close to them". And I have to again and again warn people of a "cockup cascade" - a situation in which a series of small and negligible issues or errors lead ro absolute disaster because nobody has the room for error on anything as every limit is pushed.
Much awaited, much appreciated looking forward to excellent insights as always from you.
Excellent introduction and great video about a very tragic event.

"I don't care, we just need to impress someone with something for some reason"

That opening was well made and written. Plus now I have a new song in my head :)
What's crazy is this something you'd never think about like ever for a flight delay
Increasing thrust is NOT the primary reaponse to a stall (exceeding the wing's critical Angle of Atack). It is to reduce the angle of attack immediately, by either relaxing control colomn pressure or pushing forwards.
Велика подяка за цікаве відео!
Радий,що Ви повернулись на ютуб із своїми роботами;)
If you’re a town, having an air disaster happen near you is almost as bad as having a Russian rock song named after you.
Why would a Russian rock song named after a town be a bad thing?
I know Russian music is awful
Paper Skies’ videos are brilliant. I hadn’t heard of this accident and it would be good to find more like this. I’ll definitely think about subscribing to Nebula.
In what world is a 20 degree angle of attack "normal" to any pilot? It seems simple.... if your aircraft is shaking (buffeting) and your AoA is 20 degrees, YOU ARE ABOUT TO ENTER A STALL, IF NOT ALREADY IN A STALL.
Happy to see so many new videos! Just hope you’re not burning yourself out! Take care ❤
Excellent work as always!
Very well researched video. Thanks!
Wow! Fascinating! And absolutely frightening! Great production! Thank you. 😮
So, a few weeks ago, I flew again for the first time in 18 years. Wow, somehow typing that out makes it seem like it was a really long time ago, yet 2005 doesn't sound nearly as bad. Anyways, sorry for that digression, I have been watching several channels on TH-cam that discuss aviation history and aviation incidents. I also learned to fly many, many years ago. So, between knowing how to fly and learning so much detailed information about so many aviation incidents and about the aircraft involved in those incidents, you'd think I would be terrified to fly again; but no, it had the exact opposite effect. I was confident in the aircraft and the pilots. I knew United had a solid training record and that the aircraft were well maintained, modern aircraft. I also knew what was happening at every single stage of the flight, from push-back, take-off, flight, landing, and arrival at the gate. Knowledge is power, well, Complete Knowledge is power. You have to have enough facts to about a subject to be knowledgeable about that subject. Otherwise, fear is the result.
great video, love the narration and editing 👍🏻
I have endured serious sleep deprivation before, usually on long, cross-country drives, and I've nearly dozed off behind the wheel at times too. If you're personally running on fumes, with no real stimulation for the senses for several hours, you WILL get heavy-eyed and doze off. In the cockpit of an airliner, this certainly can't be a joke either. At least in a car, you can listen to the radio or music, but in the cockpit? I'm sure the crew needs to maintain some kind of noise discipline in order to hear the radio and pay attention to other sensors, and the droning of the engines through the cabin probably makes the effort to stay awake even more of an uphill battle.
I get your point, but that's why you have at least two pilots on a plane. I've been on long car trips before too and in my experience, another person that's sitting there with you, exchanging control of the car sometimes, is way better than radio or music
I love this channel. One of the few where I get excited when I see a new video is out.
very well made. subscribed and looking forward to more of your videos
Such an excellent channel, thank you

Brilliant introduction, highlighting the depth of your research into these episodes.
This was the best intro I've ever seen on this channel, keep it up!
Didn't know about this crash before. Thanks for all those informations. The animation also are really great, good job 👍🏿
I don't want to idealize nor trivialize the issues plagueing the USSR, but 200 dead as the deadliest air disaster is actually pretty low. The Tenerife collision in 1977 between KLM and PanAm cost almost 600 lives alone, that being the biggest loss of life in an aviation accident before 9/11.
What makes this one stand out though, is that it doesn't feel like anything would change as a result, nothing was learned if they hide the truth. Usually new technologies or rules are implemented to avoid a repeat, but if they just gloss over the disastrous conditions for pilots they are just asking for the same thing to happen again.
tbh Soviet Union didn't have large commercial aircraft until Il-86 was introduced, and guys at Ilyushin actually knew what they were doing.
They didn’t have a widebody jet until 1980 in the USSR
i would not say that 9/11 was an "accident". And i guess they just literally didnt have as much air traffic and smaller plaens so less costly accidents
200 is actually a shit ton for a soviet commercial flight of this type.
@@hikarikaguraenjoyer9918 There are also disadvantages with widebody jets btw
I love how you always bring in something that's mostly unrelated to the event but you always connect it
I’ve watched a lot of air disaster channels and yours is one of the best. I really enjoy your unique style. It’s also great to hear about cases that are probably not well known in the West.
Best deconstruction of this terrible crash I've seen so far, explained in plain language without going into dull technical details. Graphics are interesting, and context of overall life in USSR at that time helps a lot. Good work! 👍

Every video you do makes me question how the Soviet Union lasted as long as it did. Seems like a slight breeze should have made everything collapse.
The soviet union lasted so long due to the women's wombs were elastic enough to produce required amount of the cannon fodder which motherland was requesting. Nowdays situation is not so bright and elastic, therefor mother-pa-russia will screwed up much quicker.
The USSR was forged in blood and the peoples resolve was hardened in WWII. Before the Nazis attacked, Stalin had starved 6 million Ukrainians and purged millions of his own people sending them to gulags. Then the NAZIS attacked and captured armies of soldiers. Stalin had the people dismantle factories and move them east of the urals. Armies of conscripts were trained to charge forward or be shot. The people endured unimaginable suffering and survived. By the battle of kursk, they had thousands of women digging trenches and a manpower and equipment advantage of 4 to 1. They threw these people into the battle and suffered horrible losses while grinding down the German army and morale. the survivors went on to storm Berlin. What came out of the war were hard men, survivors who were men and women of steel. These people had the willpower to conquer and subjugate Eastern Europe, the willpower to develop world class rocket technology and the first astronaut core. They developed the bomb, the h-bomb, and produced 60,000 warheads. Imagine the horror of hundreds of nukes landing on NYC. However, for all their tremendous wartime struggles and strength, life in the ussr was a long joyless slog. People were expected to meet their quotas but weren’t rewarded for innovation. The communists are fantastic during wartime and stagnate during peacetime. With no incentive to innovate and little use for consumer products, communists pretend to work and the state pretends to pay them. However rotten their structure becomes, kicking in the door doesn’t knock the whole thing down like Hitler infamously claimed. Likewise no stiff breeze would end the Soviets. Instead kicking in their rotten door causes a polar bear to jump out, beats the crap out of you while you empty your pistol into it in vain. Then while your lifeless body lies strewn about it barrels through your house, drinks all your liquor, has its way with your wife and drags your sons off so it has something warm to sleep on. The Russian bear then gets too drunk, enters a slumber so deep it doesn’t even procreate. So the bear just fades away into the wilderness, drunk as a skunk until Eventually someone comes around and plays the f around and find out game again. The easiest way to beat the bear is to leave it alone and let it sleep until the next war
It's the power of lying about everything and having vassal states you can poach.

Thanks for this documentary to remind us the importance to avoid drowsy driving. Actually in China, several tragic train accidents also caused by similar reason showed in this video: 83/804 accident in 1973, 179/1218 accident in 1983 and 0166/3856 accident in 1996. So, nowadays Chinese train drivers for long-range will be asked for mandatory sleep before their departure (it could be monitored). For high speed train, drivers have to kick the pedal every several seconds or minutes, their operation will be recorded by video, and their retina will be analyzed by computer to determine their conditions. All regulations are formed by accidents and tragedies...
Man, the conclusion of this video is so important, what a genius way to bring the story full circle! Those nostalgia comments on old Soviet videos always make me facepalm
listening to Paper Skies' intro gave reminded me of Air France 447, with the flight crew misinterpreting the stall warnings.
A shocking parallel with AF447. Different preconditions, similar outcome

I made a similar bet with my sister. We were riding my bicycle to tuition class when I told her I could reach the intersection with my eyes closed. I was right. When I opened up my eyes we actually reached the intersection...except we were NOT traveling on the road anymore but straight into the roadside ditch.
I love the the old aft fuselage-engined, T-tails! Specifically the larger jetliners, not the current regional jets mind you. Most of them were trijets, many others twinjets, and some of them were even quadjets. The '𝐓𝐮𝐩𝐨𝐥𝐞𝐯 𝐓𝐮-𝟏𝟓𝟒' wasn’t as sleek, or have as much the elegant lines of, say the '𝐁𝐨𝐞𝐢𝐧𝐠 𝟕𝟐𝟕', or '𝐕𝐢𝐜𝐤𝐞𝐫𝐬 𝐒𝐮𝐩𝐞𝐫 𝐕𝐂-𝟏𝟎', but it’s still very pleasant to look at. My favorite Soviet T-tails though, are the '𝐈𝐥𝐲𝐮𝐬𝐡𝐢𝐧 𝐈𝐥-𝟔𝟐', and the straight-winged '𝐘𝐚𝐤𝐨𝐯𝐥𝐞𝐯 𝐘𝐚𝐤-𝟒𝟎'.
And one unique element of Soviet produced aircraft that I find particularly enjoyable, is that the designers didn’t seem to be hampered by, or concerned with jet engine noise levels. At least from all the aviation TH-cam content I consume, the Soviet jetliner’s whirling screeches seem to be a notch above the more subdued sound of their Western counterparts; especially upon engine spool-up and takeoff run. I miss the jet engines that sounded like rocket ships. Where trips to the airport had you not just hearing the takeoffs, but feeling them all the way down into your bones. Those “blast offs” used to raise the hair on my arms, and give me goosebumps all over.
Back in the 80s nearly the entire Pacific Fleet Command was killed in a crash that happened on takeoff. The crash was not recognized publicly until years after the collapse of the Soviet Union.
Hello, I truly appreciate your uniquely useful videos of the past. I'm an aerospace engineer (AE) and I watch your videos with great interest in learning about things that happened in the past and especially what went wrong. Now, in this particular video, at 3:42 you talk about exceeding the critical AoA and you've said it was 20 degrees! Was this an angle given in units in the cockpit or the real angle of attack of the wing? Unless you know it, the angle of attack indicated onboard is the actual angle of the AoA vane relative to wing's mean aerodynamic chord and because the airflow will always go from high to low pressures, it will curve towards the low pressure, which usually is the top of the fuselage. Due to this effect, the vane will always deflect more than for an undisturbed airflow, thus showing a higher angle than the real wanted/needed reference. For this instance, all prototype aircraft and test aircraft have the AoA vane mounted on a boom ahead of the plane so that the fuselage's upward (at positive lift) circulation of the airflow won't deflect it more than wanted. Due to, let's call them laziness reasons, almost all aircraft manufacturers engineers don't bother to correct the AoA vane angle shown in cockpit with the real AoA that the plane has relative to an undisturbed airflow ahead of the plane and this is why the MIG-21 has a caution AoA of 28 and critical value of 33, when instead of 33 degrees which the vane is deflected to by the upward flowing airflow, the aircraft's wings have just 20..21 degrees of real AoA. So, coming back to the subject of this wonderful airplane (I truly like it), the Tu-154, I wouldn't wonder if the AoA indication in cockpit (if the plane has it) would show the actual vane angle which is always greater than that of the clean/undisturbed airflow. So, I just ask..., can you please confirm that the plane had a cockpit indication of 20 degrees AoA? From my experience, these kind of wings usually have a critical AoA no higher than 15..16 degrees at low subsonic speeds, around the takeoff and approach speeds, while at higher altitudes, higher Mach number and lower Reynolds number the critical AoA can decay by some degrees. Having 20 degrees of real AoA in such conditions is of real interest for me to learn about and I would appreciate if you'd give me a link or some clue regarding the data retrieved after the crash.
Kind regards!
All the numbers, including the angle of attack, were decoded from the 'black box.' Regarding the cockpit readings, the gauge malfunctioned after the second 'critical angle of attack' signal. Its arrow stuck at the 9.3-degree mark and didn't react to any further changes in the aircraft's angle. Therefore, the pilots only saw the 9.3-degree reading. I briefly showcased this at the video's start, but perhaps I should have emphasized this matter more. I didn't want to delve too deeply into technical details since my intention is to cater to a broad audience.
The mentioned 20-degree angle and others, such as the report mentioning the middle engine shutting off at a 25-degree angle, were extracted from the black box. This information was sourced from the investigation report.
Here's the link to the short report: airdisaster.ru/database.php?id=71,
and here you can access the entire crash report: vk.com/@bort85185-akt-o-rassledovanii-katastrofy-samoleta-tu-154-85311-v-raion
However, both documents are in Russian.
While gathering information, I also stumbled upon these cyclograms. aviation-is.better-than.tv/af1461%20%20%D3%F7%EA%F3%E4%F3%EA%20-%20%F6%E8%EA%EB%EE%E3%F0%E0%EC%EC%FB.htm.ru.utf8
The individual claims they are from the Flight 5143 crash, but I couldn't verify their authenticity. In the first picture, at the bottom, you can see the readings related to the angle of attack: the blue line represents the real angle ('угол атаки истинный'), while the pink line indicates the gauge reading ('угол атаки указателя').

Hello again! I greatly thank you and appreciate all the effort you've already put into the video and also to reply back to me with such a great manner and provide those links and all the details. I will read them and try to understand what the actual critical angle of attack was as a real reference angle, not just the "alpha vane" (AoA vane) angle, which is what I'm so curious about.
Many thanks Paper Skies for your implication in all the videos that you make, being an aviation enthusiast yourself as well! "Many talk, but few know"! You are among the very few to tell things right in your videos.
I recall reading an article about the Gloster Javelin, many moons ago, about the investigation into "Super Stalls" or "Deep Stalls" associated with T-tail jet aircraft. This lead to the introduction of a "stick pusher" system presumably the Tu-154 was not so equipped?
Thanks for this interesting if horrifying story. Great narration!
Paper skies is the channel I watch wind I need to stay up, it’s like audio coffee
Wow, you have to be a real genius to put a commercial aircraft into a flat spin.
I am sorry for the pax and their families.
I very much enjoyed your animation. A story well told, but oh what a terrible tragedy.
Hello, this is a great video. I could not find the Vasiliy Ershov "Crew Errors" book online, do you have a link to the source? It would help me with my university project on new aircraft operations :)
Great video as always
That Yalla song was really good.
I'm so old and even remember times when this song was introduced 😂
I love these stories that come partly from your childhood in Russian, what a great perspective
This channel is 10 times better just because of the first hand information and anecdotes from people who actually lived under the soviet regime!
Love your work keep it up!
so funny showing the crew falling asleep So in the end everybody was asleep for good! 😂
New paper skies! Makes my day every time!
Another excellent video, and another song for my soviet nostalgia list 😮
