Wire insulation is plastic, it burns. #1 source of house fires in America is a short that that starts burning the insulation. Once your insulation is on fire it can travel anywhere in the structure.

Sounds like warning signals they’re talking about. No reason something simple as that couldn’t be included on FDR.

Unfortunately probably somebody sneaking a smoke in the bathroom and then throwing it away in garbage bin.....

If this is Moslem, it was failed.

Moslems love to make sure everyone knows they did it, no question. That is their MO.

Likely just another accident.

“...torching a fatty”
LMAO! Haven’t heard that phrase in a very long time.

A report not long after the crash said that that very aircraft had made three “emergency” landings in the 24 hours before the crash.If that’s true...and it’s easily confirmed...that argues in favor of a mechanical catastrophe.

There’s nothing in avionics to burn.

Anything in there with a lithium battery?

avionics wiring and house wiring are two different animals. You cannot use house wiring in aircraft. The Teflon requirement for avionics wiring has been in place since (I think) 1978. Much of the wiring is silver or nickel alloy jacketing a Teflon or spun glass wrap. The polimide coating in the video below is rated to at least 260degrees centigrade before it melts; it doesn’t burn. Wiring meant for avionics can’t burn, arc, explode from overload or emit toxic fumes.

Perhaps the emergency O2 generators went amuck?

Here is an example of an O2 leak behind the RH side panel inside the cockpit

On 29 July 2011, a Boeing 777-200 being operated by EgyptAir on a scheduled passenger flight to Jeddah was parked on the departure gate whilst awaiting the last few passengers and completion of hold loading when a fire suddenly began at the lower right hand side of the flight deck. Despite prompt attempts to extinguish the fire, it continued to burn out of control causing major structural damage to the front of the aircraft. However, all 317 occupants were safely evacuated using the still-attached air bridge access at doors 1L and 2L. story here:....http://www.skybrary.aero/index.php/B772,_Cairo_Egypt,_2011

The Investigation could not conclusively determine the cause of the fire but suspected that wiring damage attributable to inadequately secured cabling may have provided a source of ignition for an oxygen leak from the crew emergency supply (the plane was on the ground when it all caught fire)

We take lighters all the time in our carry on when we fly. Never been stopped.

A flare in the toilet. bets?

[arthurus]

A flare in the toilet. Someone in the front end crew would have access to a flare. it is Egyptian Air we are talking about. The front end crew was rather likely to be Moslem. One probably decided it was time to do his bit for Allah.

Except it isn’t...

Yep, O2 can be nasty.

I was originally thinking of the Florida swamp crash. The airline people decided to ship some extra O2 candles back to their maintenance hub on one of their flights without reattaching and securing the safety shipping bands, and bad things happened. I think it may have been against FAA regs to ship the candles on a such a flight, regardless.

I remember borrowing a oxy-acetylene rig from a coworker. He brought it in the same day I not only got my 20lb propane tank refilled, but bought another tank.

Going home, on the highway, with 40lbs propane, and the torch rig, hoping I didn't get rear-ended. Tanks were about 2' tall, not fulled charged, whatever that comes out to.
