Today is the anniversary of the Japanese attack on Pearl Harbor on December 7, 1941. Here’s a short film of part of the actual attack. I don’t have information about its provenance, but it was tweeted by an account I trust, and it looks authentic by a number of markers.
Another anniversary is of President John F. Kennedy’s visit to Los Alamos on December 7, 1962, to be briefed on the Rover nuclear rocket program. With Russia developing a nuclear-powered cruise missile, there’s been renewed interest in the Rover program. It’s interesting to see how much less protection there was for a president back then.
