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.
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.
Covers events relating to the Operation Greenhouse atomic tests. Shows U.S. troops and men at an American outpost at Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok) in Marshall Islands. A water pumping station on the island. Boats and small planes provide transport facility on the island. The test island serve as a learning ground to U.S. Army, Navy and Air Force. Tanks fitted with measuring instruments are stationed near the Zero Tower to measure the radioactivity ,heat and pressure generated at the time of blast. Reinforced concrete buildings are build to withstand the atomic blast. Test objects like an airplane wing and fuselage section are positioned to study the effect of blast on them. U.S. parachute troopers stand beside a transport plane. Commander and his crew at the Joint Task Headquarters in Perry Islands,USA, make final decisions before the atomic test on Enewetak. Unmanned B-17s and fighter jets take off at night to collect valuable information during the blast. View of the atomic bomb explosion and its effect on the buildings at the test island.
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.
Atomic bomb test (Operation Greenhouse) on the Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok) in the Marshall Islands. Animation shows the effects of an atomic blast. Men suspend various reading instruments from a bomb-shaped plastic balloon that will provide valuable readings at the time of atomic blast. Banks of high speed cameras are planted close to the tower holding the fissionable material (Zero Tower). Radioactive measuring instruments are planted on the islands. Scientists and technicians perform a last minute check of the necessary instruments before leaving the island. A view of the Zero Tower. Men leave the island and detonate the bomb. Mushroom cloud of the atomic blast at a distance. Men in boats at a safe distance watch the explosion wearing protective eye glasses.
Covers events relating to Operation Greenhouse. Atomic cloud generated by the atomic test conducted at the Enewetak Atoll (sometimes spelled Eniwetok or Eniewetok) in the Marshall Islands. Atomic investigators perform analysis, tests and research of the radioactive samples collected from the atomic test site, in their laboratories.
