Why did the South Tower fall first?
Engineers suggested that the south tower of the World Trade Center collapsed first, even though it was hit by the second plane, because the fireball caused by the crash was larger and because the plane hit the corner of the building, rather than the center, where there is more structural support.
What caused the trade centers to collapse?

The analysis shows that if prolonged heating caused the majority of columns of a single floor to lose their load carrying capacity, the whole tower was doomed. Despite optimistic simplifying assumptions, the structural resistance is found to be an order of magnitude less than necessary for survival.
