Operation Sandstone, the third American series of atomic bomb tests (tests number 6,7 and 8) at the Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok) in Marshall Islands,Pacific Ocean. Shows development of an atomic test site at the Enewetak Atoll. American personnel dressed in protective suits perform tests and scavenge wreckage on the Eniwetok Atoll. View of men at the shore and distant convoy of U.S. ships at the horizon. An aerial view of the atoll. American army officials map the operation, back at home. Shows unloading of supplies at the shores of Enewetak atoll. Areas are cleared of trees and foliage. Coral soil is leveled by machines. Cement and tar added to harden the surface. Men detonate underwater obstacles. Aerial view of a causeway joining the two islands. Shows tent city for living quarters and quonset supply huts on the island. Workers build cubes of reinforced concrete. Tower in the middle of the lagoon. Man lays underground cables. View of a tower holding fissionable material on the island. Scenes of American scientists working in the Atomic Energy Commission laboratories, exterior of an American university and Mexico's desert.
Deployment of atomic security and testing measures in Enewetak Atoll in the Marshall Islands (sometimes spelled Eniwetok or Eniewetok) before the Operation Sandstone atomic bomb tests. Exterior of the Argonne National Laboratory near Chicago, Illinois. U.S. Atomic Energy Commission laboratories in Los Alamos,Oak Ridge, Hanford and Brookhaven. American flag post and a distant tower (Zero Tower) on Eniwetok Atoll in the Marshall Islands. Loading unloading of cargo at shipyard in Long Beach,California. Convoy of U.S. ships heads for Enewetak. Scenes of men aboard the ships. U.S. troops in Eniwetok Atoll deploy security measures and plant testing and recording instruments near the Zero Tower. Several types of photo cameras in a workshop . Troops mount high speed cameras on an aircraft.
Nuclear detonation on Bikini Atoll in the Pacific Ocean as part of the Operation Red Wing. A resultant mushroom cloud. Scenes of landing of several USAF-aircraft like B-52,B-47,B-66, B-57 on a United States AFB situated on the Eniwetok atoll (sometimes spelled Enewetak or Eniewetok) in Marshall Islands. Shows the aircraft carrier USS Badoeng Strait in Northwestern Pacific Ocean. Several US-airplanes like F-84F, F-101, B-52 and B-36 can be seen on the AFB. Maintenance crew can be seen working on a B-52's (Stratofortress) engines. Men working on the nose and wing section of a F-101 Voodoo. Technician working on the F-101's electronics equipment, opens its nose dome to reveal photo panel radiation gauges. Airman removes motion picture camera from the nose of F101. Technicians work at the instrumental panel of a B-57. Radiometer attached at tail section of B-66. Technician removes dust for radiation sample. Technicians work on the horizontal stabilizer of B-47 tail section.
Covers events relating to Operation Greenhouse. Scenes of American personnel working on the test islands of the Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok). View of various bomb proof reinforced test buildings. Several scenes including man building wooden structure, Zero Tower, vessel in water and master control station. Men prepare to leave Eniwetok Atoll. Scientists and technicians make a last minute inspection of all the necessary instruments before leaving the island. Ships loaded with men move to safer water. Men prepare to trigger the atomic bomb on the Eniwetok Atoll. The bomb explodes resulting in a high mushroom shaped atomic cloud. Men of Los Alamos return home after a successful mission.
Covers the events just after the atomic bomb test (Operation Sandstone) on the Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok) in Marshall Islands. Atomic cloud generated after the atomic explosion moves away from the atoll. Unmanned B-17 planes that have collected valuable traces of the atomic cloud are made to land. Radioactive data is collected from the B-17s by remotely operated forceps. A tank, remotely controlled from a helicopter,digs out sand to collect samples on the Enewetak Atoll. Men dressed in protective clothing search the rubble on the atom blasted island. Valuable data is collected from the island and sent to the laboratories in America for analysis. Scientists perform analysis of the collected data, helping in the further development of atomic energy.
First air drop test of a thermonuclear weapon. The weapon was dropped from a USAF B-52 bomber (not seen) that flew from Fred Island, Eniwetak (sometimes spelled Enewetak or Eniewetok), on May 21, 1956. View appears to be from an aircraft flying above altocumulus clouds, below higher stratiform layers. The film begins with a complete whiteout from the initial fireball. As that subsides, local stratiform clouds take on a rosy hue and the center fireball is seen rising above them. As the fireball rises, it takes on a somewhat hemispherical shape, flat on the bottom, from which a straight stem-like column extends toward the ground. The light of the explosion slowly fades and complete darkness ensues. Official accounts state that the intended ground zero was directly over Namu Island, but the flight crew mistook an observation facility on a different island for their targeting beacon with the result that the weapon delivery was grossly in error. The bomb detonated some 4 miles off target over the ocean northeast of Namu. As a result essentially all of the weapons effects data was lost. ( Note: According to ancillary reports, the delivery error resulted in blast overpressures and thermal effects on the 6 structural response targets between Iroij and Namu Islands, greatly exceeding specifications for any use in scientific military modeling of high yield aerial detonations. Plans for graded damages analysis failed when all the structures collapsed. Effects cameras also failed from the intense fireball heat.)
