Jeremy, you have NO IDEA how much the US Gov't tries to cover up. Please read the book Body of Secrets by Bamford. In it, it describes countless plots by the US Gov't, better said Pentagon. Operation Northwoods during the Kennedy Admin. was a whole plot to gather support to overthrow Castro. It called for the sinking of friendly Cuban refugee ships, bombings in Miami and DC, blowing up the space ship of John Glenn, civil plane hijackings by Cubans,and even getting a group of college students bound for Jamaica on Spring Break to charter a plane from a CIA aviation company (of course that is held secret). The plane however is a drone that flies over Cuba and sends out a pre-recorded message that says the plane is under attack from Cuban MiGs and then explodes in mid air. This transmission would be recovered by the Int'l Civil Aviation Org'z in the Western Hemisphere so that they can tell the press and the US Gov't what happened to the plane.
All of this was supposed to strike up public support to go to war w/ Cuba.
