With all the meteorite sightings in the past couple of weeks, I'm thinking the plane got hit by one. They travel three times the speed of sound when they enter our atmosphere, so the impact would obliterate the plane instantly. That would explain why the image on the control radar screen intlantly disappeared.

i am enclosing a link to the BBC news site so you can keep in touch with this tragedy. All we know at the moment is that it has gone down. With all these rogue states firing missiles about one can only wonder ?

It went down off the Vietnam coast.

It went down either buy human error or mechanical failure. We'll know more in the next few days.

A north Korean SAM hit it

Perhaps in went into a time worp.

Time travel into the past or the future.

IDK but the conspiracy nuts have already come up with thier explanations.
