Lieutenant Walter Haut was the public relations officer at Roswell in 1947, and was the man who issued the original and subsequent press releases after the crash on the orders of the base commander, Colonel William Blanchard.

Haut died last year, but left a sworn affidavit to be opened only after his death.

Last week, the text was released and asserts that the weather balloon claim was a cover story, and that the real object had been recovered by the military and stored in a hangar. He described seeing not just the craft, but alien bodies.
