Was there a bomb in the World Trade Center attacks on September 11?

No. There was no bomb in the World Trade Centre attacks on September 11 2001, although the terrorists on board the planes may have *claimed* that they had a bomb to gain control of the plane- it is doubtful that we will ever know. The buildings were brought down by terrorists flying planes into them, which in turn caused burning jet fuel to weaken the steel in the building enough that it buckled under the weight of the building and tragically collapsed.
