in a youtube video of TWA flt 800 which i previously posted (very realistic portrayal of what the cabin was like after the explosion) they show the cabin lights and emergency warning system being on after the nose fell off the plane and the plane was ascending then falling

wouldn't the separation of the nose have cut off the lights and warning beepers or not necessarily?

would depend on what type of cabin illumination system is used and where the electrical system to power the lights is located. On my itty-bitty-jet the cabin emergency lights were charged in two ways, solar charging through the unit, or via the aircraft electrical system for times when the batteries weren't able to be charged via sunlight (i.e. night time, etc). Some of our birds also had a standard electrical emergency light system that relied solely on the aircraft electrical system to power...

how many minutes do you think it took from the first explosion on TWA 800 to get reported to the proper authorities? Was it the pilot (David McLean) of the other plane who saw the explosion and flash of light who reported it? Or those on the ground? which authorities get contacted? curious about how this all works

The CVR pinpoints the catastrophic failure of the aircraft at between 20:31:03 EDT (the last spoken, though unintelligible, word) and the end of the recording 9 seconds later. Less than 40 seconds after that, the first eyewitness report of the disaster came in - by a 737 airline pilot reporting the fireball, to Boston ATC.

NTSB was notified of the incident at ~20:50 EDT.

Most of the lights, especially the emergency lights in the cabin are going to be powered from the hot battery bus. The location of the battery on that aircraft was actually in the cockpit near the flight engineer's panel. It's actually not entirely unreasonable to think that any lights forward of the explosion would have turned on and remained lit. Ordinarily, emergency equipment is engineered to turn on as its fail safe. As well, the warning indications and lights in the cockpit are often engineered the same way.

Another way to look at it would be to think about the aircraft as though it had lost all power (all four engine generators and the apu gone). Obviously, since that would be an emergency, you'd still want all your emergency lights and warnings to work. So, the aircraft is designed with that taken into consideration.

Though I guess I never thought about it, that would really be an eerie thing... The back half of your airplane just exploded and yet, there are these reassuring exit lights and warnings "guiding" you to safety.

when flt 800 exploded and after the nose came off, the broken plane pitched upward. I don't remember the reason the youtube video gave for that but then what happens to the jet fuel when a flame roared thru the cabin? does it all turn to flame? if so then it wouldn't be jet fuel thats propelling the plane upward, it would be some kind of velocity or something to do with the pressurized air leaking out of the plane?

the video said when the wing tips came off this caused the plane to hurtle to the sea.

i guess what im trying to ask is any liquid jet fuel still permitting the plane to run and fly?
