“The island of Elugelab is missing.”

“I made one great mistake in my life when I signed the letter to President Roosevelt recommending that atom bombs be made but there was some justification; the danger that the Germans would make them.”
On November 1 1952, the United States detonated the first full-scale thermonuclear device on the island of Elugelab in Enewetak Atoll, in the Pacific Ocean, as part of Operation Ivy. It was the first full test of the Teller–Ulam design, a staged fusion device. Follow us on Twitter: @INTEL_TODAY

The device was designed by Richard Garwin, a student of Enrico Fermi, on the suggestion of Edward Teller. It had been decided that nothing other than a full-scale test would validate the idea of the Teller-Ulam design.
The test was carried out on 1 November 1952 at 07:15 local time (19:15 on 31 October, Greenwich Mean Time). It produced a yield of 10.4 megatons of TNT, around 700 times the explosive power of the weapon dropped on Hiroshima seven years earlier, killing 160,000 people.
Ivy Mike set the infamous record of the largest explosion until then and would be the fourth largest U.S. nuclear test ever conducted.
