We were guinea pigs: Documentary puts Atomic Veterans in limelight

I have a friend who was involved in the Atomic Bomb tests. He helped design it. He's an inventor of lots of gadgets, some that work, some that don't. He's 90 years old but sharp as a tack. One of his inventions is a ceiling fan that runs without electricity. It runs using magnets.
Anyway:

1958, Frank Farmer was a young sailor on the USS Hooper Island, one of many deckhands who took part in an operation so secret, they couldn’t talk about it for almost 40 years.

Afloat in the Pacific, the ship participated in Operation Hardtack I, a series of 35 nuclear tests conducted in the throes of the Cold War arms race with the Soviet Union. Farmer personally witnessed 18 of the explosions.
