In December of 1984, Jamie Shandera, (pronounced JAY-mee SHAN-dehr-ay) a Los Angeles television producer, received a manila package on his doorstep. He and writer/researcher Bill Moore had been looking into government knowledge of UFOs. Moore had made a deal with elements of U.S. intelligence community that was supposed to net him classified documents and information in exchange for his services as a "mole" in the UFO community. The package was not delivered with the regular mail, even though it bore a postmark from Albuquerque, New Mexico. Shandera had already retrieved his other mail when he heard his screen door closing and found a bulky envelope in the space between the screen and front door.

He called Moore and they opened the package together. In the envelope were two more envelopes. The last one contained a roll of black and white 35mm film. They went straight to Moore’s darkroom to develop the roll. What they found was a series of pictures of an official-looking report which came to be known as the Eisenhower Briefing Document. The rest is history.
