Don't forget, DMG, that they also hit the Pentagon and the fourth plane was evidently head toward the Capitol or the White House.

Had the fourth plane hit Congress in session, the destruction of the WTC would have seemed almost like an afterthought.

Which raises the question, once the alleged Bushite plotters had decided to blow the Pentagon, why even bother with an immensely more complicated plan to destroy the WTC as well? ('Spiracists also claim that the fourth plane was just additional "cover." Why would they need that? Of course, some say it was just a coincidental crash that the evil ones pounced on for added publicity.)

The Pentagon alone would have given plenty of justification to attack al-Qaeda, and as DMG suggests, a lesser plot would have meant a far smaller chance of detection. (No demolition experts secretly placing shaped charges that "investigators" could later suss out, etc., etc.)

'Spiracists may not be "insane," but their 9/11 theories certainly are.
