That observer's pilot life: 6 years sick and then this
He must have been quite ill to be out for six years. He must have been very "rusty" at that point.
@@eucliduschaumeau8813 He has had retraining to make sure he is still fit to fly :)
There's a lot more to this accident than is depicted in the video. Delta and Northeast merged in 1972 and both airlines had DC-9s, but they were considerably different. They had different auto-pilots made by different manufacturers, and different flight directors. One airline had single cue flight directors (bat wings, depicted in the video), and the other had dual cue flight directors (cross hair needles). For a period of time after the merger, the two pilot groups only flew the DC-9s that they were familiar with at their previous airline. Delta gave the pilots a list of differences between the 2 aircraft types, but no other training, assuming "pilots are pilots" and "DC-9s are DC-9s" and they'll "figure it out". I'm pretty sure that the day of the accident was the first day that the 2 pilot groups were integrated and this was the first time the accident pilots had seen a Delta DC-9. They were unfamiliar with the auto-pilot and the flight director. The short flight, allowing the jump seat rider to participate in the operation of the aircraft, much confusion, not sure what the flight director was depicting, and the marginal weather was a recipe for disaster.
As I understand it, the DC-9 involved in this crash was a ex-Northeast plane that had had the flight director and other instruments replaced with ones similar to those in Delta DC9s. I also recall that, apart from the display, the basic difference between the Northeast and Delta flight directors was in the operation of the selector control. Basically, the flight crew (ex-Northeast except for the observer) moved the switch as they would for the older unit. As a result, the reading they got misled them, as noted in the video.
😊
Thank you for covering this. Living just north of Boston, I still remember this crash very well. My friends and I were playing in their back yard when their mother stuck her head out of the kitchen window and said "Hey, there's been a plane crash at Logan." We then went inside and watched the coverage on the local TV station (Channel 5 - WCVB) for a couple of hours. Many years later, the magazine Airliners featured a very good article about the crash. Note that the full NTSB report, which was quoted several times in the Airliners article, has never been made available to the public on the NTSB web site.
It's funny how you only notice the mistakes just after going live. In the crew intro the Captain and FO labels should be the other way round 🤦.
Had it been a 747, you'd have crashed it.
I was working at Logan that day, awaiting the arrival of our SR flight and we heard the communications on our office radio. We knew an employee who was on that flight. Also there when the IB DC-10 went down.
Great video! I was hired by Delta in '88, not long after the Western merger. Started as an FE on the 727 and they spent a lot of time on "differences training" for the 727-232 (Delta) and 727-247 (Western). Years later as an FO we acquired 727-221s (Pan Am) and 727-225s (Eastern) and again we had "differences training". Things have changed a lot- for the better.
My aunt Janice Wilson of Houston, Texas was a stewardess on this flight. I never got to meet her.
Fantastic video. As a lay person, your explanations and the images (such as the glide slope depiction) really helped me understand what was going on and also terminology. With other channels, I constantly have to pause the video to look something up.
I remember it well. One of those pea soup humid summer days here in the northeast. Ten years later I happened to fly with a gal, whose Grandma had died in that crash. We were delayed at Logan, by engine troubles, which we had no problem with them delaying as long as needed to fix the problem ... :-/
How about the businessman who deboarded before the flight? Lucky man!
Take your time with these! The quality blows me away every time
Short flights in jet airline operations add significant demands on flight crews. I spent a month last summer flying two trips a day, four days a week, with those two flights being 20 minutes (sometimes less) between lift off to touch down. In the month we had everything (weather) from clear skies and unlimited visibility down to minimum acceptable visibility necessary to conduct the published instrument approach. By the end of the month we were really good at it-but I spent a lot of time studying for this flight sequence before the first time we flew it as it is a summertime only (seasonal) flight sequence. Getting "behind the jet" is always bad, on a short flight it is even worse. As the saying goes: don't ever let the jet get someplace that your mind hasn't already been before.
No you didn't
Daaaaamn these graphics are phenomenal! Another brilliant production and I'm stoked to see how much traction you're gaining 😊
With your “Three Greens” LOGO. The Nose Gear Green Light should be at the Top of the other two. This indicates the position of the nose wheel relative to the other two Main Gear! Only a small observation Sir!
SAKUA 3 SAKURA SAKURA
737 aft overhead panel has the lights in the mains over nose gear configuration. Many planes have their own indicators that aren't the standard primary in passenger jets by Boeing and Airbus. 3 green lights in a horizontal line would also be accurate. Standardization is a rather modern concept.
@@kdawson020279 I only flew the 737 for 3500 hours, and the 747-400 for 9000 hours! Standardisation is what keeps people Alive in the air!
@@pikachu6031 Absolutely. You were 6 times more likely to die on a commercial flight at the beginning of the jet age than today.

I still contend the FO and Observer had switched seats for this particular segment, as the checklist flow and the captain’s momentary slip in acknowledging the first officer’s name suggest a conscious altering of normal cockpit verbal pattern. Bear in mind too, that the FO and Observer also had very similar last names, further obscuring a clear identification who was actually in the right hand seat. This was a particularly opportune moment to do a little switcheroo with minimal risk of getting caught. What better time to let the returning pilot anxious to get back in the game a little innocent stick time on a 10 minute 4,000 altitude puddle jump? The comment by the captain “just fly the airplane” to my ears sounds like something you’d say to a newbie getting reacquainted with hand-flying muscle memory vs a seasoned FO who is accustomed hand flying approaches while also monitoring instruments etc. A seasoned FO doesn’t need reminders to focus. A six-years-rusty newly returning pilot, on the other hand, most likely would.
Keep in mind that the F/O only had just over 200hrs in the aircraft type, whilst the Capt had nearly 1,500, so it may have been quite innocent to address him like a newbie and being old enough to be his father could've been a factor in attitude too.
Indeed. We’ve learned a lot about human factors and accident-preventing procedures and conduct since the 70’s. Additionally, ground proximity warning systems (now several generations since) would have alerted to being below the glide slope.
Not to mention the automated ra callouts.. it shocked the crap out me the way it just silently flew into the ground like that.
I get they had altimeters but damn...
I like seeing this channel grow,and I’m trying to contribute to it as much as possible by liking all your videos!!great quality content!!!!
Always leave a comment for the algorithm 😗
I love aviation. I almost goty polit licenses but the us at sent me for duty on South Korea for service and I only had only had only one hour to go before my solo. That's life I guess. Don lackey bonneau,s.c.😀😀🤔🤔
Wow all I thought about was the man who de-planed. So so sad for those lost. So many people have had to die for the airlines to get to where they are today.
idk about anyone else, but every time I see the thumbnail of this video it takes me a second to find the wings of the plane.
Lmao me too i thought it was a space shuttle when i first scrolled past it
Great job putting us in the situation in real time, amazing how fast you can get behind the aircraft. 👍
The DC-9's Livery is the livery which is new, 73' Delta had the new livery? Damn, i didn't know that.
been watching since your first man, keep it up
Your videos stand out from the others. The CVR is a huge plus. Thank you for putting these together.
These videos are incredible.
I now realize how bad everything else is.
More commentary, but the graphics and communication are great, thanks
Hadn't heard of this crash before thank you for your excellent presentation.
I was waiting for this
Three Greens means left, right, and nose gear is down.
Correct!
@@3Greens Except you got the logo upside down :(
@@Bren39 😦
Descent on the ILS with no valid glide slope indication? Scary!
Glad I never had to fly with a crew.
another great video.
Great video and for a change one I have never heard of before - most of the videos done are great but why do the same crashes over again and again? I love your narrations and explanations also this is a great new - to me - channel
It strikes me how lacksidaisical the comms were-- hardly any readbacks or use of the callsign. The ATC thought they taxied off, but there was no handoff to ground control?
Right? I kept thinking " is he talking to me" lol
I'm glad you pointed out that much of their convo. would've violated the sterile cockpit rule today. I thought the same thing. Enjoyed the vid. 😉👍✌️
Great video! I really look forward to new ones and rewatch old ones. In my opinion, entertainment and educational value is on par with Aircrash Investigations.
Thank you sir. I really do appreciate all of you who come back for each video 🙂
@@3Greens Thank you for producing great content. Must take a tremendous amount of time. Not too early to start a Patreon! :)
Oh wow, I wonder how that business passenger felt after he heard the news….I probably wouldn’t fly again tbh.
Nice job, 1st vid of yours watched, won't be the last!.
A 10 min flight? That's insane
Not a stabilized approach - go around. Basic airmanship is completely ignored.
Wikipedia places partial blame on ATC, although the final report may not have.
The pilots are flying the plane, and are doing so incredibly incompetently.
Approach clearance was delayed slightly, but ATC isn’t flying the plane. The pilots are, and are doing a terrible job of it.
Sad. Very sad.
They were not flying the plane.
As I remember the excepts from the NTSB report contained in the Airliners article about the crash, the NTSB determined that ATC's communications were potentially confusing, but there was no direct evidence to show they may have led to the crash.
never heard of a 10 minute flight before is it worth it lol...
While flying into Orlando, our plane diverted to another airport due to storms.
Some people DID get off, presumably driving to Orlando.
The delay wasn’t long, and the trip to Orlando took about ten minutes.
They should have intercepted the glideslope from below, to avoid a false glideslope due to lobes/reflections. They were too focussed on landing. A go around would have lost speed and altitude safely.
Can you make the video of Trans world airline flight 800?
Where do they get these narrators with thick accents for American accident reports? Well done, anyway. Thanks.
I also noticed the crew's voices sounded unnatural also. 🙄
@@gilbertfranklin1537 Naturally. Actual cockpit voice recordings are not released to the public. The transcript was reenacted for the video. I real life, I’m sure it would have sounded a lot more natural, but also probably quicker and harder for the video’s audience to understand.
Two of my classmates were on this flight.
Why didn't the GPWS sound? Because it was in approach mode?
I guess they put the Captain in the left seat sometime after 1973.
Wait… did you say *10 minute* flight? How was that ever economical for Delta?
Thank you for the video. Vincentfam
Yes yes one on the bennffffatron
Why in the view did you have an arrow showing the captain sitting on the right and first officer on the left? That’s incorrect. Also that approach light system looks like a British Calvert system and that’s not used in the US
Nitpicky are you
Capitan sits on the left. Bru
Poor radio read back.. Very poor
Northeast yellowbird.
For some reason, I can’t get this video to play, which is disappointing as it looks very interesting. It’ll play for a few seconds, then stop. I can advance it manually, but the same thing just happens again 🤷♀️
Internet connection, most likely.
The captain check airman and his sidekick observer were both acting like Joe Cool instead of doing their jobs as professional crewmembers. Sucks for the passengers having to die because of the captain was acting like a jackass.
Pilot is on the left
I hope flight crews today are a lot more professional and competent than these guys were.
I love tuning in! You desperately need Promo'SM!!!
Lol they talk like npcs in a video game
3 Greens....your videos are good & well put-together but the in-flight stuff when they talk to the tower could be much better. To be honest, It sounds like something out of a 'Thunderbirds' episode! Why not just buy two cheap walkie-talkies & record your voice-overs thru' them....needs to be crackly & almost hard to follow if it's to be realistic. I mean, you use subtitles anyway so why does it have to sound so unrealistically clear?
Yay
Accent is pretty thick... technical inaccuracies and non-idiomatic language.
The livery on the aircraft is incorrect for the time period.
Much of the flight deck graphics are incorrect.
Jet bridges and airport graphics at Manchester are not correct.
The approach was to rwy 4R and the graphics show runway 14/32.
And so on and so on. Much wrong with this video and is a poor representation of the actual accident.
Sure looks like 4R to me in multiple places.
Not surprising that the simulation software doesn’t have a full historical database of liveries.
The point of the crew missing the GS intercept, being fast and unstable on final, being off the localizer and high on the GS (until the passed through it) were pointed out, as well as the irregular conduct of checklists by a jump seater.
It is also an MD80 and not a DC9
@@N1120A if you looked on his pilot certificate at the type ratings, guess what it would say :-)
Bro were you there ffs
