The buildings failed at or near the aircraft impact sites, very close to the fires. If there were explosives, it brings up these questions:

-- How were the explosives planted? In what offices were they planted? Who had access?

-- How did the planes hit the exact part of the building where the explosives were planted?

-- How did the wiring to the explosives survive the impact/fire?

-- Explosives are rarely stable at high temps, why didn't the fire destroy the charges?

-- How were the charges triggered when the building was so damaged?
