You missed my point. Ok. So assuming they blew it all to hell... Why bother flying the planes into the buildings? I mean, that creates a HUGE risk of getting caught and a huge risk of something not going according to plan. Why not just do whatever you say they did to destroy the buildings (demolition, energy beams, whatever) and forget about the planes? Buildings demolished. Public scared/outraged. Mission accomplished. Why bother with the planes?
