Major items still missing in pictures in the public domain...
A. Fuselage barrel section between wing and tail... (two window rows aft connected to the tail section),
B. Substantial part of the vertical tail and rudder,
C. A large number of seats,
D. ....
As far as i have seen ... No clear evidence of bomb damage on any available picture...
No pictures of burned seats than can shed any light on the direction and extent of the fire in the aft section (point A.)...
From what is published you would expect quite a flash or short flashfire... In what appears to be a very short time. So how would a small bomb explain that. Cutting the APU fuel line of a shut off APU, does not deliver that ? ... Wings and cwt seem pretty complete? ... Did this specific plane configuration indeed carry fuselage tanks apart from the cwt, then these would be a more likely source?
Bomb versus fuel-tank explosion scenario discussions are not new. And appear to be never ending even years after final reports are published.
The engines are pretty close to the wing ... You can see them in a number of pictures taken from the main impact site. They separated rather late. They look pretty clean... and not like having had a catastrophic failure... Kicking out (both) fans is indeed quite unusual...
Another thing is, that we do not know what the site looked like just after the crash. Recovery of the victims has of course been a priority in the early stages.
Too many possible scenarios open at this stage... Is my impression... Which statistically speaking is no surprise
