Here is a website for a company that has produced some nice documentaries on many phases of nuclear testing (I own all but one of them!):
http://www.vce.com/trinity.html
These are the folks that made the "Trinity and Beyond" documentary.
"Atmoic Journeys," a nice look at nuclear testing throughout the United States (Did you know that underground test explosions were also conducted in Alaska, Colorado, and Mississippi? "Nukes in Space," about space nuclear explosions. "Atmoic Film Makers," about the people who documented the test explosions. And "Nuclear Rescue 911" about Broken Arrows--accidnets involving nuclear weapons.
A very fascinating look at the history of a technology that has changed thw world.
