And could also indicate that pressurization of the cabin triggered a major break-up of the aircraft due to serious internal structural cracks. What we don't know is, are the charred wings and forward fuselage a result of fire while in flight or after crashing into the ground?
Based on ground wreckage photos, it appears the main wings hit the ground intact with the forward fuselage all the way to the nose cone.. Would this be possible in a bomb scenario? UNLIKELY!
I heard another small tidbit today: The plane was porpoising for a short while before it broke up. Radical up and down, then breakup. If a small bomb was in a rear cargo compartment in checked luggage (or snuck there by a jihad symp ground crew) it could destroy or damage the tail/horizontal stabo. The pilot might have a brief period of fighting for control. I remember Air ALaska that crashed trying to emergency land at LAX. The cheap counterfeit Chinese worm screw that controlled the horizontal stabo jammed. They tried to fly it by alt means, and did.....for a while.
Anyway, the damage and the black boxes should tell the tale, if Russia tells the truth etc.
