(worthless argument)
let me paint you a picture
sturdy structure, steel outer and inner beams.
not-so-sturdy stucture, rectangular.
plane hits at an angle that cuts nearly an entire outer beam side, structure is weakend.
plane slowly starts collapsing, due to hollow structure, building's weight is off.
the other side of the tower is bending, breaking due to low-elasticity,
thus causing the jenga effect.
same with pther tower, but boosted by the shockwaves of the first tower.
its really not hard to understand
