Obviously missing airplane parts and victims prove this was a wormhole created by the Large Hadron Collider.

WOMD from 2009 / 2010 .... that didn’t (don’t) exist

Another theory I just saw on Facebook: It could have been shot when it was at a lower altitude by something that didn’t destroy the plane immediately.

Aliens?

Aliens?

A: Probably not. A local affiliate of the extremist Islamic State group has claimed it brought down the aircraft, but intelligence experts say they don't have weapons capable of reaching the 31,000-foot elevation the plane was flying at when the disaster occurred.

I don't believe anything they say. Who knows what isis picked up in Iraq after we pulled out?

Maybe the pilot was getting drunk during the flight while getting their typical BJ and dropping bombs when something went wrong?

Unplanned contact with earth?

Having been to Sharm where the plane took off from, and seeing the folks there, it is very likely that the baggage loaded on the plane has something extra in it. Either timed or altimeter triggered.

Since the tail of the aircraft separated, the structural integrity of the airframe failed - most likely from rupture. At cruising altitude, there is a huge pressure differential.

Sounds like a short in the Center Fuel Tank to me...
