Just because one goof committed perjury in front of congressional committee means nothing. The "U" in UFO/UFA stands for "unidentified". It stops being unidentified when you know what it is. It's nothing new. The U.S. air force investigations into UFOs from 1954 to 1969, called Project BLUE BOOK, are all publicly available from archive.gov, including the 700+ cases that actually remained unidentified. It's so fucking public that there has been more than one TV series about it and a shit-ton of documentaries.
