"Surrounded by darker, deeper ocean waters, coral atolls often glow in vibrant hues of turquoise, teal, peacock blue, or aquamarine. Belize's Lighthouse Reef Atoll fits this description, with its shallow waters covering light-colored coral: the combination of water and pale corals creates varying shades of blue-green. Within this small sea of light colors, however, lies a giant circle of deep blue. Roughly 300 meters (1,000 feet) across and 125 meters (400 feet) deep, the feature is known as the
Great Blue Hole." (Massive

If the radiance of a thousand suns were to burst forth at once in the sky, that would be like the splendor of the Mighty One... I am become Death, the destroyer of worlds. ---> part one and
Part two of Operation Crossroads, one of many atomic testing operations conducted during WWII, documented extensively on film and preserved in excellent condition here at the Archive. For further viewing:
Operation Ivy, the testing of the first hydrogen fusion bomb.
Operation Cue (1955 version), testing bomb damage done to housing and infrastructure.
Special Delivery, a look at the preparation and technology, especially planes, used for the testing.
Duck and Cover, a classic safety film from 1951 detailing the best schoolyard response to a nuclear attack. Caution! Interesting, disturbing, and at least an hour's worth of viewing!
