Am I the first to observe that there are no indications of explosive combustion in the photos we have seen so far. Given that most modern luggage is synthetic- nylon/polyester/vynl, plastic , one is forced to note that NONE of the luggage on shown shows any sign of heat, melting, burning, or molecular/ physical change.
The visisble red bag would perhaps show such if it is synthetic and had been subject to combustive force.
Therefore, unless they find chemical residue from a small, low powered combustive event, it is unlikely that this dmage was explosives related. My humble view is that we are likely to eb looking at a possible aleleged corrosion under the galley floor or FOD from ramp vehicles- or a moving LD container.
Of note is that in the internal galley/door 2 right shots, the internal trim on the forward edge of the door psot has been damaged. This may explain a possible initial cabin crew report of a door going or a main door warning light flashing on the flight deck.
Given that the interior door panel/post is showing damage, it is clear that the force of the so far unknown event did go thru the structure adn it is further evidence just how lucky QF are- and how stong Mr Boeing makes a 'plane.
At least it was not the old cargo door issue hey....
And yes, those frames are snapped sharp and randomly in an outward direction - very interesting indeed.
