“A plane disappears without a call from the pilots.
1. Terrorist bomb
2. Catastrophic disintegration of airplane
3. Pilot deliberately crashing plane”
Those are about the only options
I lean towards #2 If it were terrorist someone would have taken credit for it.
Those planes have a LOT of carbon fiber in them. When carbon fiber parts fail it is catastrophic and sudden.
My guess is some part was damaged while doing maintenance or make ready
Very few terrorist groups actually claim credit for their actions.
There was an expert on TV today that showed what would happen if a cabin door flew off. He said the in rush of air would likely cause others holes. The air is -66 degrees and as it rushed in it would be a thick fog and the pilots wouldn’t have time to react. He said this would scenario would take about 6 seconds.
