The image provided by the United States Army Air Corps shows an aerial view of the Mauna Loa eruption on November 21, 1935, captured by the US Army 11th Photo Section. Thomas A. Jaggar, the founder of the Hawaiian Volcano Observatory, asked US Army Air Services to send planes to bomb a Mauna Loa vent to disrupt lava channels. He said the bombing helped to “hasten the end of the flow,” but Howard Stearns, a US Geological Survey geologist onboard the last bombing run, was doubtful. In his 1983 autobiography, he wrote: “I am sure it was a coincidence.” (Photo | AP)
