Bikini H-bomb video clip. Awesome. That super thin, perfectly circular, disk at the bottom. The remnants of the bomb casing at the top. 1’ 15”, no ads.

We had a retired Coast Guard ship here as a museum ship that participated in radiation effects on ships tests in 1946 or 47 Bikini Atoll blasts. I think it put out marker buoys.

Pretty cool.
