For those unfamiliar, Valujet Flight 592 experienced an incredible fire in one of the cargo compartments from expired oxygen generators. The oxygen generators would heat up to close to 300 degrees Celsius while releasing plenty of oxygen to everything around it up. From testing done by the NTSB, it's very likely temperatures in the plane exceeded 3000 degrees Celsius. The situation inside the plane went from a bit of smoke in the cabin to a ragin inferno within less than a minute. The thing that really perplexes me is that there was a point where everybody was talking about the fire and you could hear screaming in the background, and then almost instantly there was dead silence, where the only thing audible was loud rushing air, but this was while the plane was still in the air. Is it possible that everybody just passed out from hyperthermia within just a couple seconds?

Here's a transcript of the audio recording. I wish we could hear the actual audio recording for ourselves.

The smoke made them pass out
I find it odd that it went from screaming all throughout the plane to dead silence within a couple seconds, with the only sound being rushing air. Even the NTSB agents were perplexed by this, as they state in this documentary. I wonder if that rushing air was caused by the fire.
pure oxygen and open flame causes rapid oxidation, this is how thermic lances (which cut through steel like butter) work and what killed gus grissom and the Apollo 1 crew in the space program of the 60's. If you watched alien covenant they recreated this incident on James Franco's character.
It most likely simply burned a hole in the hull that then blew out to a much larger hole via a depressurization explosion.
oops forgot to post vid link of thermic lance
the only thing that is happening with this lance is a flame being fed pure oxygen btw. The odd thing is that oxygen itself is not flammable, as I already said it causes rapid oxidation however
There exists a wienerpit voice recorder on every plane that's always recording. It actually took a lot of work to find the black box with the voice recording of that flight. They might have just been incapacitated due to a combination of heat and smoke, but I find it odd that it went from an environment of several people screaming and the flight attendant speaking about the fire to dead silence in a matter of just a couple seconds.
Yah I wont even speculate on how or why that was because that is all it would be is speculation. I was only responding to your query about "rushing air" and what likely caused it
I don't think cabin depressurization is as catastrophic as you think it is. There's usually a loud noise, but I don't see how that would result in a sound of rushing air. I don't think there were any major holes in the plane until after it crashed. That's why I'm wondering whether the fire somehow caused that sound of rushing air.
>I don't think cabin depressurization is as catastrophic as you think it is
I never said it was catastrophic, I said it is what caused the sound of rushing air you described. In fact a aloha air lines plane flew back to its departing airport with half the cabin blown off once. Many planes dont even have pressurized cabins including WWII bombers. Pressurized cabins really only matter for high altitude flight
https://en.wikipedia.org/wiki/Aloha_Airlines_Flight_243
That's what happened on Aloha Airlines Flight 243. The pressure inside the cabin basically made the roof of the plane blow off. The cabin was still in tact when Valujet Flight 592 crashed, but it wasn't that high in the air, and maybe there were some holes made in the cabin that resulted in air being whooshed around, but I still think it could've been caused by something else.
Only sources of air in the plane are
>compressed bleed air from engines
>pilot oxygen bottles supplying their masks
>passenger chemical oxygen generators supplying their masks
Pilot oxygen flasks are normally positioned beneath the floor under the wienerpit, maybe they got cooked and one of their over-pressure valves opened?
>The pressure inside the cabin basically made the roof of the plane blow off. The cabin was still in tact when Valujet Flight 592 crashed
Yes but they were at 24,000 feet. You said yourself the ValuJet flight wasnt at cruising altitude yet. A depressurization event at a lower altitude wouldnt be as violent as the difference of the pressure on the outside and inside isnt as severe. It doesnt take much of a cabin breach to create the sound of rushing air mate. It doesnt even require a rupture in the hull, just a break of the pressurization seals
btw to add a little more to this and bump your thread, "cracking a window" in a car produces a much louder "wind rushing" sound then rolling it all the way down. If it cracked the door seals, or windshield seals it would produce a very loud noise, deafening in fact, traveling at those speeds
poke a fully extended balloon with a pin and it will pop, poke one only 1/4 extended and it will simply deflate
Actually I will speculate a little here. In a rapid oxidation environment it is a "flash fire" of tremendous heat. Like a fricking crematorium. It is entirely possible that the entire plane was fried instantly. The Apollo 1 incident killed the entire crew in a matter of a few minutes. Fire in a pressurized environment also causes immense pressure which is why the astronauts couldnt open the latched door to escape. It is likely the fire literally roasted everyone on the plane alive in a matter of seconds building an immense amount of pressure what is then what blew open the cabin causing the rushing air. Take with a grain of salt.
ps There are better recreations of the Apollo 1 incident than the one I posted
>It is entirely possible that the entire plane was fried instantly.
The pilots had stopped speaking around a solid thirty seconds prior to the last words of the senior flight attendant, so it's possible that the pilots, along with a lot of people in the cabin, had already lost consciousness by that point. The fire was getting stronger at an exponential rate as the oxygen generators started activating, so maybe it instantly got to a point where everybody just passed out due to incredible heat within just a couple seconds, because it really went from several people screaming to dead silence.
yes or it could have even been the pressure that caused them pass out like a hyperbaric chamber
depressurization caused everybody to pass out instantly
No, that's definitely not what happened. They hadn't even reached cruising altitude. The fire was introduced to the cabin after only a few minutes in flight. Explosive decompression of an aircraft cabin usually isn't deadly in itself, unless the plane crashes as a result.
"The Theory of the Leisure Class: An Economic Study of Institutions" is a treatise of economics and sociology published by Norwegian-American economist and sociologist Thorstein Veblen in 1899 which will explain the lack of competence displayed by NTSB agents.
Not sure how the mic works on planes seems to be push to talk and the flight attendants have access to comms. Pilots may have been trying to do something and weren't talking until they passed out. Passing out usually isn't a instant thing, you slowly fall asleep slowly losing consciousness they were probably thinking weird thoughts about sleep and needing to sleep despite their situation. The final noise may have been just been their limp bodies pressing buttons by accident.
Maybe they had a flashover? Air temp + oxygen escaping into the cabin could have turned the atmosphere into an inferno in a second or less.
Just for background context
stronauts Grissom, White, and Chaffee, clad in their spacesuits inside their Command Module (CM) at Cape Kennedy’s Launch Complex 34, were conducting a countdown simulation ahead of their planned Feb. 21 launch. Their mission, officially called Apollo 204 but better known as Apollo 1, was to be the first piloted Apollo flight. As they would on launch day, the astronauts and ground crews sealed the three hatches of the capsule and pressurized it with pure oxygen at 16.7 pounds per square inch (psi), slightly higher than atmospheric pressure. At 6:31 p.m., a flash fire broke out inside the cabin. Within seconds, rising temperatures and pressures caused the CM pressure vessel to crack, releasing flames and smoke onto the launch pad’s service structure. The astronauts, in vain, attempted to open the inner hatch, while the pad crew valiantly worked to open the outer two hatches, their attempts hampered by dense smoke and heat. By the time they opened the hatches, the crew had already perished. Later that night, after photographers fully documented the scene, recovery crews removed the astronauts’ bodies from the spacecraft and took them to a nearby medical facility. U.S. Air Force pathologists conducted examinations, concluding that the astronauts died of asphyxia from carbon monoxide and other toxic gases resulting from the fire. The burns they received were likely survivable.
