Well, I don't want to post something without some corresponding evidence.
But the consesus on some message boards is that the WH was indeed the last target, and that after seeing 3 remote-controlled planes crash into civilian-rich targets and the 4th on its way, a Canadian general said "go ahead, charge me if you want to " and ordered the plane to be shot down. Hence the inability of ANYONE to go on record with what happened that day, since half of Canada knows the truth.
There were no bodies, because the planes were switched, of course. (Bodies don't play well on tv, and you need tv for a true psyop to be successful.) The planes that hit the towers, those people could die there, because it was all fire and distance. We sure wouldn't want bodies on the white house lawn/ pentagon lawn, so those planes had to be switched. Those people on board, who knows where they ended up (although we know that one passenger called 911 from the plane, in ILLINOIS).
