MountainBear: So I don't believe in the bomb hypothesis--not based on evidence so far.
But don't you think there is additional context that increases the likelihood of it being a bomb:
- Russian involvement in Syrian/ISIS conflict
- ISIS takes responsibility for plane
- UK and US suspect bomb based on intelligence
- Action taken to change aircraft travel through airport
- ISIS Paris attacks
- Reports that CVR sound signature = bomb
- Complete almost instantaneous in-flight failure of commercial aircraft is extremely rare
- Russian government states it was a bomb (I would not judge its current actions based on MH170)
Seriously, in this case you have to look in the opposite direction of everything right now to think it wasn't a bomb.
