At least I have a suspicion...
We know 4 planes were involved in 9/11, one went down in PA, leaving 3.
It is interesting that I found this today, because the recent reports of the Cleveland Airport Mystery have made me reconsider the plane swapping and bumble planes theories. Here is a link to the Bumble Planes theory if you are unfamiliar with it:

Anyway, in a nutshell, the bumble planes theory suggests the planes were switched midair with drones with the drones being the aircraft actually involved in the attacks. This explains why transponders were turned off and why the planes appeared to take such sharp turns on the radar. The question remains, what happened to the original planes??? One of the possibilities the Bumble Planes mentions is that they were flown out over the ocean and destroyed.
Anyway, I'm sitting hear watching my CNN videos from 9/11. It is currently September 12, 2001, somewhere between 9:15 and 9:30 in the morning and the following David Ensor, CNN National Security Correspondent comes on withbreaking news and states the following:
U.S. officials confirm that three planes in the airspace of Western Canada near Vancouver are currently being tracked by Canadian officials, it is unclear what they are up to and who is flying them.
Now we all know that Osama's relatives were being shuttled out of the country that day compliments of President Bush, however, would they have flown over Canada??
Furthermore, Cleveland, site of the Cleveland Airport Mystery and possible destination of the 9/11 planes if they were swapped, is near the Canadian border. Could the 9/11 jets been flown out through Canada, into the Pacific ocean and destroyed????
