A former air force officer who claims UFOs disabled the nukes at a nuclear weapons base has accused the Pentagon of a cover-up - and wants to tell Congress the truth.

He was speaking after Scott Bray, the deputy director of Navy Intelligence, admitted the Unidentified Aerial Phenomena (UAP) task force has not looked at what happened.
