On April 24, 2006 an article appeared in the New York Times newspaper describing the firing of C.I.A. employee Mary O. McCarthy for leaking secrets to the press.   McCarthy was fired Thursday, April 21 after admitting she had leaked classified information to reporters about secret C.I.A. detention centers and other subjects, CIA officials said.

The C.I.A. is believed to have many classified UFO documents.  Certainly given the above scenario the likelihood of any future UFO document release is diminished.
