The U.S. Air Force document was revealed by NICAP.

Quote from the article:
“The U.S. Air Force has sent its commands a warning to treat sightings of unidentified flying objects as ‘serious business’ directly related to the nation’s defense, it was learned today.

Vice Admiral R. H. Hillenkoetter (Ret.), a committee board member and former director of the Central Intelligence Agency, said in a statement that a copy of the inspector general’s warning had been sent to the Senate Science and Astronautics Committee.”
