I'm wondering if this is an attack, too.

I'm also wondering if these are suicide pilots with empty planes. Or if somebody has screwed with the electronics and re-routed the signals for instrument approach so that commercial planes on automatic instrument approach automatically fly into the buildings.

No self-respecting pilot would come in on instruments on a beautiful clear day.
