The motion picture "Oppenheimer" is the story of American scientist J. Robert Oppenheimer and his role in the development of the atomic bomb at Los Alamos Laboratory in New Mexico.
The movie opened in theaters July 21.
As scientific director of the Manhattan Project that created the atomic bomb, Oppenheimer played a leading role in ending World War II. He was a physics professor at the University of California but owned a ranch in New Mexico. Oppenheimer wanted a secluded spot for the government's secret laboratory, but also one with an available work force. Los Alamos seemed right to him, and it became home to the lab originally called Project Y.
"Trinity" was the code name the U.S. military used for its project to detonate a nuclear bomb. After years of work, Oppenheimer and his team successfully detonated a nuclear bomb that they nicknamed "The Gadget" at 5:29 a.m. July 16, 1945. "The Gadget" was the same design as the bomb known as "Fat Man" that would be detonated over Nagasaki, Japan, less than a month later.
The Manhattan Project was top secret and did not become public knowledge until after the bombings of Hiroshima and Nagasaki.
Newspaper coverage lacking
The July 16, 1945, explosion was seen as far away as El Paso. There was no report of the explosion in the El Paso Times on July 17. The July 18 edition carried a two-sentence explanation from the Associated Press:
ALAMOGORDO (AP) — Explosion of an ammunition magazine on the Alamogordo Air Base reservation Monday morning, heard and seen for many miles, was reported by William O. Eareckson, commanding officer. There was no loss of life or injuries to persons, Eareckson said.
Meanwhile, the El Paso Herald Post ran a lengthy article on the explosion, still describing it as an ammunition magazine explosion.
Army ammunition explosion rocks Southwest area
Great blast near San Marcial lights El Paso
An ammunition magazine containing a considerable amount of high explosive and pyrotechnics exploded at 5:30 a.m. in the New Mexico desert near San Marcial on a remote section of the Alamogordo Air Base reservation.
No one was hurt.
The blast was seen and felt throughout an area extending from El Paso to Silver City, Gallup, Socorro and Albuquerque.
Many persons saw a flash light up the sky, like daylight, and felt earth tremors. They thought an earthquake had struck.
William O. Eareckson, commanding officer of the Alamogordo Air Base, release the following statement:
“Several inquiries have been received concerning a heavy explosion which occurred on the Alamogordo Air Base reservation this morning.
“A remotely located ammunition magazine containing a considerable amount of high explosives and pyrotechnics exploded.
“There was no loss of life or injury to anyone, and the property damage outside of the explosives’ magazine itself was negligible.
“Weather conditions affecting the content of gas shells exploded by the blast may make it desirable for the Army to evacuate temporarily a few civilians from their homes.”
El Paso men going to work at 5:30 a.m. said the flash illuminated Mt. Franklin. E.R. Carpenter, Louie Ratliff and Jack Couleham, riding down Alabama avenue, said the whole sky was ablaze with light.
Mr. Carpenter, mechanical superintendent of the Newspaper Printing Corp., said many persons called the newspaper’s composing room to report seeing the flash and hearing the explosion. Callers asked if a meteor had fallen.
Big light in sky
L.R. Lessell, Gila forest headquarters superior, said rangers reported the shock was felt throughout the Mogollon mountains.
Rangers at Chloride reported the blast lighted the sky brightly in the area of San Marcial. The blast was followed by a terrific explosion, like a detonation, rangers said.
Forest rangers, believing that an earthquake had struck, checked with Alfred E. Moore at the Smithsonian Observatory on Burro Mountain. The observatory is near Tyrone and 800 feet high.
Mr. Moore confirmed the flash, saying it was distinctly visible at the observatory, but said the shock was unlike earthquake vibrations. The observatory head has experienced earthquakes in South America and Mexico.
Silver City shaken
Silver City residents reported three distinct blasts were felt there. The shock cracked plate glass windows in downtown buildings.
“The blasts sounded like heavy claps of thunder,” Don Lusk of Silver City said. “Houses shook. People were roused from sleep by the noise and tremors.”
Mrs. H. E. Wieselman saw the explosion as she crossed the Arizona–New Mexico state line. She was en route to El Paso from California.
“We had just left Safford, and it was still dark,” Mrs. Wieselman said. “Suddenly, the top of high mountains by which we were passing were lighted up by a reddish, orange light.
“The surrounding countryside was illuminated like daylight for about three seconds.
“Then, it was dark again.
“The experiences scared me. It was just like the sun had come up and then suddenly gone down again.”
Front seat at sky show
Ed Lane, Santa Fe railroad engineer, was at Belen, N.M., when the blast occurrent.
He said he had a front seat to the greatest fireworks show he ever had seen. The blast was in the direction of San Marcial and seemed to be only a few miles from Belen, he said.
“I was coming to El Paso,” Mr. Lane said. “My engine was standing still. All at once it seemed as if the sun had suddenly appeared in the sky out of darkness. There was a tremendous white flash. This was followed by a great red glare and high in the sky were three tremendous smoke rings. The highest was many hundreds of feet high. They swirled and twisted as if being agitated by a great force. The glare lasted about three minutes and then everything was dark again, with dawn breaking in the east.”
