Anniversary of Bikini Atoll atomic bombing

Friday marks the 55th anniversary of the United States dropping the first airborne hydrogen bomb on the Bikini atoll in the Pacific Ocean. The test was a success and symbolized a huge leap in the nuclear arms race.

According to the History Channel, people who witnessed the test remarked the resulting fireball "measured at least four miles in diameter and was brighter than the light from 500 suns."
