"Flight 93" and the Plane That Crashed at Camp David

Excellent research from Woody Box on: Norman Mineta, the alleged Cheney shootdown order, the flight 93 that allegedly crashed in Shanksville, the flight 93 that was headed to DC and the flight 93 that crashed near Camp David.

UPDATE: Interesting tidbit about Camp David in this old NYTimes article (via StevenWarran):

Controllers also say they were told to watch for planes heading for Camp David, the presidential retreat in Maryland. Unlike the World Trade Center and the Pentagon, Camp David would be hard to spot from the air, but it is clearly marked on charts, because the airspace below 5,000 feet is off limits to civilian planes. But because Camp David is close to Washington and a hijacked plane's target is unknown, it would be hard to say whether a plane headed toward that location actually intended to go there, controllers noted.
