Commemorative postal cover time and date canceled at 8am, 7 December, 1941 at Aiea post office, about 1mile from Pearl Harbor. This was canceled as the opening bombs were falling.
I just learned about this today, it was a clue on Jeopardy!
Today we went to a free showing of the subject documentary. It was in support of the Space Museum and Grissom Center.
It is currently in 5,000 sq ft in Bonne Terre, MO. They are looking for 50,000 sq ft. The city of St. Charles, MO has offered them 20,000 sq ft and it looks like the move is going to happen.
Back to the documentary. It is a first class production and I recommend it to everyone. It runs about an hour and hits on all of the US space programs, Mercury through Artemis, but it focuses on the Apollo I disaster.
