Salut Petrov,

Et tu crois aussi que l'impact de l'avion a pu causé la démolition de la tour no.7?
Bien sûr que la tour 7 n'a pas reçu de Boeing, mais elle a quand même été violemment percutée par des centaines de tonnes de débris provenant de l'écroulement des deux tours géantes. Si tu avais été à sa place, tu aurais eu du mal à rester debout.

WTC Building 7 appears to have suffered significant damage at some point after the WTC Towers had collapsed, according to firefighters at the scene. Firefighter Butch Brandies tells other firefighters that nobody is to go into Building 7 because of creaking and noises coming out of there. [Firehouse Magazine, 8/2002] According to Deputy Chief Peter Hayden, there is a bulge in the southwest corner of the building between floors 10 and 13. [Firehouse Magazine, 4/2002] Battalion Chief John Norman later recalls, “At the edge of the south face you could see that it was very heavily damaged.” [Firehouse Magazine, 4/2002] Deputy Chief Nick Visconti also later recalls, “A big chunk of the lower floors had been taken out on the Vesey Street side.” Captain Chris Boyle recalls, “On the south side of 7 there had to be a hole 20 stories tall in the building, with fire on several floors.” [Firehouse Magazine, 8/2002] The building will collapse hours later.
En plus de ce violent choc mécanique (pas loin d'être aussi violent que recevoir un Boeing), l'incendie n'a pas été mineur.

The backup mechanism (that should have shut off the fuel oil pumps when a breach occurred) failed to work, and the fuel oil (diesel) was pumped from the tanks on the ground floor to the fifth floor where it ignited. The pumps emptied the tanks of all 12,000 gallons of fuel.
12000 gallons, c'est plus que la capacité des réservoirs d'un Boeing 757 (
de 11276 à 11489 gallons, selon le modèle).
Bref, la tour 7 a subi
des dégats mécaniques majeurs et
un incendie majeur. Et tout ça, dans ses étages inférieurs, ceux qui supportent le poids de tout le building.
Que te faut-il de plus ?
