My bad, it wasn’t the first. But my dad’s still my hero:)
It was operation crossroads.
from the web:
It was the first test of a nuclear weapon after the Trinity nuclear test in July 1945, and the first detonation of any nuclear device following the Fat Man detonation on August 9, 1945. Its purpose was to investigate the effect of nuclear weapons on naval ships.
And they did sit around and watch it with no protection. Too bad I don’t know how to send pictures from my phone. Took pics of his pics for my siblings
Your dad should be your hero. :)
There’s a good documentary you can get...narrated by one Captain James T. Kirk.
