- If you came here from Crash Truck Dash Cam #2, the description below is substantially similar. The one significant late addition to that video's description was a photo album, which can be found at tiny.cc/AA383Pics (case-sensitive link redirects to a Google Drive album).
~~~~~~~~~~~
On October 28, 2016, at 2:32 p.m. CDT, a Boeing 767-300 (registration N345AN), scheduled as American Airlines flight 383 bound for Miami, Florida experienced an uncontained right engine failure and subsequent fire during its takeoff ground roll on runway 28R at Chicago O'Hare International Airport. The flight crew aborted the takeoff and stopped the aircraft on the runway and an emergency evacuation was conducted. Of the 161 passengers and 9 crew members onboard, one passenger received serious injuries during the evacuation and another 19 experienced minor injuries. The airplane was substantially damaged by the fire.
Here is some more information you likely have not heard elsewhere:
-It took firefighters ten hours to completely stop the fuel leak. To capture leaking fuel, firefighters first used eight containment pools, and eventually placed a fuel bowser beneath the wing.
-Airport firefighters saw this fire from the station and started responding immediately, prior to notification from the tower
-One of the first units on scene included a firefighter who had been with Chicago Fire Department for 36 years. He had never before responded to an aircraft fire and was scheduled to retire the following day. At 11:00 in video #2 you can hear that firefighter saying "I finally got my fire! Luckily no one was hurt!"
-Not all equipment was functional during the incident. Cameras which had recently been tested malfunctioned, and one of the high-reach extendible turrets on a crash truck was out of service.
-One of the ejected turbine disc fragments pierced through the plane's wing and continued thousands of feet through the air, eventually falling through the roof of a UPS shipping facility, bouncing off of (and locally shattering) the floor, and finally landing on a loading rack... over 3,000 feet away. Check out the photo album at tiny.cc/AA383Pics (case sensitive, link redirects to a Google Drive album).
-Firefighters used over 24,000 gallons of finished foam (720 gallons of 3% AFFF concentrate) on this fire.
-The estimated cost to repair runway damage due to heat and gouges from flying turbine shrapnel was close to $1,000,000. It was necessary to cut a section of runway out of the ground.

Those are MASSIVE streams of water; they aren't fire hoses, they are re-directed rivers.
6000 liters a minute if I recall. So close to a river =)
its not water actually. some sort of mixture i forgot what its called. yea its quite the stream though
bs the mixture is generally called foam though the exact type can vary from department to department.
It’s not water- it’s foam 🤦🏾♂️🤦🏾♂️🤦🏾♂️
@@lesteveman4462 and purple K
With all due respect to the other ARFF crews at aerodromes across the country, ORD's is one of the best (IMO). They are a unit within CFD at both ORD and MDW. Those Striker 4500s (produced by Oshkosh) have 4,500 gallons of water plus many gallons and pounds of foam and chem. I have seen other videos of this incident from other dashcams and the videos can be a fantastic learning tool for others, not just in Chicago. It seems the (ARFF) crews on this incident did a tremendous job. Those mounted turrets are amazing. I did not know though until watching this video and after reading the description that the damage to runway was that extensive.
That makes sense...we have 2 KMEs 1500gwt..400 foam..1250 gpm...lucky we have not had to use them yet..Columbus Ga.
That wind though,..
Purple K has been around for a while. In 1965 I had just started my first aircraft mechanic's job when i attended a fire-fighting class that included use of Ansul 50 and the brand-new super product, Purple K. It did the job. I hate to be critical of the firefighters who did such a great job of putting out this fire, but.... At some point, they should have realized that the fire was re-igniting because of the red heat in the engine turbine section. The only way to get agent in the turbine is through the core engine exhaust pipe. One truck attacking from directly behind the engine would have been more effective than the three trucks spraying from the front. Obviously, with a fire of that intensity, you need a lot of foam everywhere, but over and over I have seen films and videos of aircraft accidents with firefighters spraying foam on the outside of the airplane when the fire was inside, or otherwise putting it where it was wasted. I once took a group of firefighters at Denver Stapleton around the airplanes available and showed them such things as fuel tank and oxygen bottle locations, openings and vents, and so forth. I was rewarded with a ride in a monster truck and a close look at a kerosene burn at the fire pit. Never forget the tremendous heat radiating through the black smoke surrounding the column of fire above the pool. Scary stuff.
I think you maybe referring to De-icer fluid, it contaminated streams local to the CVG airport before they built a pad with a recovery system.
sometimes they spray and cover the aircraft in foam and the ground so passengers can survive. The aircraft is not important! If you get soaked and run from a burning aircraft and live, it's a good day.
g
FYI they had two crash rigs shooting foam from behind the wing into the back of the engine.
George Foltz No he is taking about the PFAS that is in the foam.
You learn something new every day.
I thought purple K was just a dry chem.
Who knew you could make kool aid out of it.
i never heard of it till today. shows how much i know about firefighting. even had a job once as a fire watch at boeing. go figure...
Purple K is dry, it’s not mixed to make foam. There is a specific type of liquid that is called Aqueous Film Forming Foam that is inducted into the water running through the tank that makes the foam.
Firefighting systems can either just use water or activate the foam pump and system and use foam mix in the same hoses and monitors that are used for water. They can shut down the system and use just straight water again. Almost every fire engine made today has up to a 1200 gallon water tank and then maybe a 20-50 gallon foam tank that just holds the AFFF liquid.
But Purple K is strictly a dry chemical powder. Making it wet is like wet flour and won’t do anything.
There are specific systems used on ARFF rigs that have monitors and huge compressed air cylinders to shoot out dry chem like fire extinguishers do. But at the levels and distance the water shoots out.
my introduction to firefighting was in my uniform and combat boots, on the roof of a 3 story with raging diesel in the basement and steel grid floor and staircases inside. "You don't quit until this fire is out". no protective gear, no breathers, nothing. our 2 teams put it out in less than 5 minutes. i still had melted grid marks on my shoe soles many years later. i felt heart and soul for the truck crew in front of the engine. good vid!
I was just amazed to see that plane on fire at Nellis Air Force Base how many people in their entire life of ever seen a plane on fire a little camera in my phone was not working very good that far away and then when I found out it was just a practice drill I erased it but what an amazing thing to view in real life in real time
Too bad you could not just pull up about 20 feet away and pump a stream right thru the whole engine so foam came out the tail pipe. By the looks of things the fuel was reigniting due to heat still present. Maybe on of the piercing booms needs a "Slide Cutter" to get the slide out of the way too.
Sweet any videos of the British airways fire at Vegas?

Cool video ...good thing they have a large assortment of crash trucks. I saw the purple k...nice job...but why did the trucks return to back into the station so soon?...was it to fill up on water and Foam....if you have water you never leave the scene....or get out of the drivers seat..
brad davenport - Yup, water. in the videos you’ll see most of the trucks last around three minutes of flow time , which makes perfect sense for the 6x6 trucks as they carry 3,000 gallons of water and flow 1,000 gpm from their bumper turret on high.
The station has a rapid overhead refill system, and partway through the incident one of the engines stretched a few hundred feet of large diameter hose from a sort-of-nearby hydrant.
They do, they're underground. Aircraft and metal hydrants don't mesh well if they come into contact with eachother.
Stubborn fire!
Footage shows just how effective this foam stuff is doesnt it?
Thirty years ago the FAA thought the term "crash truck" sounded too negative so they changed it to ARFF, Aircraft Rescue and Firefighting.
Best decision they made too
Imagine if they had become airborne...
Bad feeling when you roll up, putting hundreds of gallons of water on a fire and it doesn't seem to be doing anything. I remember shipboard firefighting school. Fog is your friend for a fuel fire. When you don't have any AFFF (or whatever they call it now).
Purple K does the job, but a mess to clean up.
Had a delivery for new gate that a newbie ramper accidentally discharged inside the
Tug maintenance bay. What a mess… then they turned on a water hose to clean it up and made it worse!
I'm no expert but I think if you aim more to the right it work better due to wind.
Those trucks can empty their load of foam in minutes but how long does it take to refill the trucks?
Two three minutes with water and foam if you have proper hookups, did this for four years in USAF and then as a civilian airport crash crew.
Whoa!
Little duck tape for the wing and this bird should be in the air in a hour.
Lol
This isn’t allegiant! It will take at least 3 hours. Delayed in 30 minute increments of course.
That will buff out
If it was spirit airlines yes they would do that
@@TheMeanestGuy that’s the spirit
Purple Nurple!
Da darf man doch die Einsatztaktik kritisch hinterfragen.
Wenn man sich diese Wassermengen ansieht ...offensichtlich auch AFFF....dann wurden gigantische Mengen wirkungslos von Aussen auf die Triebwerksverkleidung appliziert. Löschwirksam war nur, was in die Turbine ging und darunter den brennenden Treibstoff gelöscht hat. Warum wurde kein Schwerschaum verwendet oder in der Initialphase des Einsatzes Pulver um zunächst die Flammen schlagartig zu ersticken? Oder haben diese Fahrzeuge keinen Schwerschaum und Pulver mehr?
I understand there was an evacuation, but when did that occur? I see nobody but firefighters out on the runway and ramps deployed, so are we to assume that the passengers got far away from the plane that quickly?
Now thats 4v1
Get closer. No one with a branch!
No cesa el fuego
Where was the Purple-K application?
The entire footage is purple k application. Purple k isn't actually purple when it's mixed with water.
klackattack that is AFFF Not Purple K powder!
The PKP kicks in at 1:16. Note the color change. The powder and foam are shot together. We call it a purple slurrie
The problem with foam and powder is the lack of the ability to cool off the over heated metal.
I relate to this incident when I was trying to fight a fire on the truck wheels caused by driving on a brake jam. The powder would put out the flame but the hot break parts would ignite immediately the moment I switched off the powder. I had to eventually pour water to cool off the parts and fire wet out. Sure, the brake disc cracked but the 40 feet truck was spared.
I wonder if a small stream of water could be shot at the engine after foam has fought of the main flames and neutralized most of fuels. I fear despite the presence of the foam fire fighters, this kind of repeated flaming of the engine could ignite an intact fuel tank and cause an all devastating explosion..
After initial dry chem, foam and water knockdown, it would have been real effective to apply METAL X, the engine would not cool down because the magnesium in the engine and wing structure was burning causing the running fuel to ignite. Was the fuel shut off or transferred from that engine, it seemed to still run out of the wing.
Foam is just as capable of cooling as water is, AFFF even somewhat better because of its reduced surface tension. Shooting water into an object that has just been extinguished by foam would be fatal sicne you'd disturb the foam blanket and allow oxygen back in. Washing down foam blankets and then blaming the foam for the reignition is a classic mistake.
AFFF does cool. It’s only 3% foam mixed it with the entire amount of water that would normally be coming out of that monitor. Dry chem offers zero cooling since it’s the same as throwing flour or baking soda on a pan of cooking oil.
But foam is good because it cools, and creates a film to coat. It’s not like the early foam systems that was just bubbles that they used huge fans to create to starve the fire of oxygen, like blowing bubbles as a kid.
These are a lot of older trucks. New trucks being made have thicker glass and nozzles above the glass that rain water down over them, and automatically turn the windshield wipers on as soon as the pump system is flowing water to keep the radiant heat lower inside the cab.
Crash crews run in where angles fear to tread.
Airport crash crews where I work run in the morning, lift weights in the afternoon and cook dinner at around 6, they run the trucks once a week for the cameras. For instance the guy retiring had 36 years without an aircraft fire, aviation is the safest mode of transportation it's just spectacular when it goes bad.
@@michaelallen1396 I am talking about Navy flight deck fire fighters !
,,Eventually,, that's all
"Cross the streams!' (betraying my age)
Cool practice drill. No people in site
Fun fact CPD units assigned to the airport are the only CPD vehicles in the fleet with red and blue Emergency lights. By state law, CPD is required to use all blue emergency lights due to the population of the city. But vehicles assigned to the airport cannot use all blue because blue is used by the FAA on runways and taxiways at airports.
So it’s very odd to people in Chicago seeing a CPD unit with red and blue lights, thinking it is not a real police vehicle.
Wind is enemy number one using foam.
Yes.. but you may use low expansion ratio foam...
that's AFFF, not purple-K
Commissar0617 - Did you watch the whole video? (Starting around 1:15 the purple stuff flowing from the Hydro-Chem nozzle is definitely Purple-K.)
oh? i thought that was shadows.
Commissar0617 - Haha! There’s a sort-of-related lesson learned from this response. One of the crash trucks tried flowing Purple-K and assumed that something was wrong with the system when they didn’t notice any color change in their high flow stream. (As a result they turned off the Purple-K.) It was ultimately discovered that everything had worked fine, and that the presence of Purple-K may only be obvious when mixed with water/AFFF on low flow.
@@Commissar0617 good excuse if you were colorblind to purple.
im not, but it didn't really look purple
Where is the truck crash?
That’s ‘Crash’ (responding To A) type truck! But when your in the thick of it... who cares what you call your fire 🔥 putter outer!!
Lol 😂
I wonder, these 6x6s must be able to traverse the fields in between the runways right? Why are they zigzagging on the tarmac, wasting valuable minutes?
No they definitely cannot transverse the grass between the taxiways. Those rigs are very heavy and unstable (on one of the other videos your can hear the tip alert sound when they take the corners too fast). If they tried going off the tarmac they'd get stuck at best. Also they had a full ground stop on the field. Only things moving were the emergency vehicles.
@@n.jersey8256 I don't know about those particular models, but airport crash tenders are built and tested to have superior offroad capability, exactly to be able to do that (check out a few Rosenbauer videos). It is for the above mentioned reasons of traffic safety but also that they still are faster on tarmac than offroad that they do not cross the grass.

CO2.......
Pissing in the wind... Your in a big ass Oshkosh fire truck , the cab seals up pretty good and is relatively safe .. some fire retardant qualities are built in so instead of practicing you technique of daintily misting your prize petunias how about getting 20 feet closer and giving that engine the money shot...
I'm no nozzle nut but I have a general grasp of the physics of fire including liquid fueled fires .. and a pair of eyes... My powers of observation tell me half of the video I've seen of fire fighters airport or otherwise kinda make me question whether or not they really want to put out the fire as quickly as possible... I love all you firefighters out there.. being a first responder is a hard row to how... We all know it's long stretches of boredom, endless training, in an always alert posture with spurts of action ... But I'm starting to wonder if a little inadvertent subconscious sandbagging occurs.. ya know, when it's just material/ property cooking down and lives are out of risk? .. maybe a little sadistic toying around .. minimum impact maximum visual drama to thrill the gawkers .. maybe extend the rare opportunities to work those real world experiences a little bit longer.... Hey, not judging .. just floating the theory .. I mean c'mon ! Nobody loves pyrotechnics and fireworks like a firefighter and that is a bonafide universal truth ... Give a firefighter a roman candle , you can't knock the masterbatory grin from thier face with a halligan tool . ( incidentally thier favorite problem solver / door key ) You ever see or go with a firefighter on a camping trip.. yeah how can you miss em right ? Your looking to toast a few marshmallows and he's trying to signal the international space station ..
Well , I guess it's not much to ask for society as a whole to blindly disregard these lunatics firebug tendencies in trade for the sacrifice , risk and unwaivering bravery and selflessness they give us every day...
You sound like a nozzle nut to me
You have no clue what you are babbling about
