Ground-level view of April 15, 1955 atomic test at Frenchman Flats, Nevada Test Site in Nye County Nevada. Test code-named "MET" -- Military Effects Test. In this footage, the 400 foot shot-tower on which the 22 kiloton nuclear device is set can be seen in the foreground prior to detonation. Rocket trails or "streamers" become visible to the right of the shot tower before the explosion. After the brilliant flash, which completely vaporizes the shot tower, an immense fireball becomes visible, which churns skyward and begins to cool and blacken. The fireball quickly begins to develop into a mushroom cloud.
United States conducts nuclear tests at Nevada test site in Nye County, Nevada. Looking down over ground 'O'. Area obscured by brightness of white light, it dissipates. Fireball seen after the atomic blast. Mushroom cloud moves straight up from the 'O' zone with its narrow trunk. Cloud billows up on top. Top section of mushroom cloud. Trunk of cloud, and top with red appearance. Grey curling smoke below the cloud. Thin mushroom cloud with red smoke ring like a halo, hovers above the long neck of smoke. Red smoke ring hovers above the blast area.
One of the Operation Teapot atomic tests at the Nevada test site in Nye County, Nevada. B-36H Aircraft in flight at almost 37 thousand feet. Several contrails in sky. Aerial blast goes off high in sky forming a white fireball, it darkens quickly. It looks like a doughnut with a large hole in its center. It closes up fast and produce an odd-shaped circular smoke cloud. It has a appearance of a doughnut with a shallow area in the center. (Note: Because of the extreme high altitude of this air-drop test , the device was retarded, by parachute, to allow the B-36 time to travel a safe distance before detonation.)

Area obscured by the brightness of the flash which dissipates immediately. Fireball rises up from the desert floor. Dust cloud on the desert floor. Fireball boils skyward churning its way upwards casting a shadow off to the right.

United States conducts nuclear test at Nevada test site in Nye County, Nevada, during Operation Plumbbob. Desert floor, mountains in the background. Area obscured by the brightness as shot Owens blast goes off in the background. Circular ring of smoke covers the ground area. The fireball and smoke churns upward. The top part of the mushroom cloud rise slowly and moves outward. Cloud dissipates from the blast, it mingles in with natural clouds.
