When the late-night talk-show host James Corden asked Barack Obama about UFOs last month, there was as usual an air of nervous joviality surrounding the subject. Bandleader Reggie Watts pressed him as well and Obama, as if relenting, admitted two things. Firstly, that he could not divulge all that he knew on air; and secondly, that the slew of footage released by the Pentagon in the past two years showing UAP — ‘unidentified aerial phenomena’ — is in fact real.
