The U.S. Army dirigible Roma crashed and exploded just west of here during a test flight on 21 Feb 1922. The crash, the deadliest involving a U.S. hydrogen airship, killed 34 out of the 45 officers, crewmen, and civilians on board. Roma, purchased from the Italian government, was based at Langley Field in Hampton and had been plagued with troubles since arriving in the United States in 1921. An investigation blamed the heavy loss of life on the use of hydrogen, a highly inflammable gas. After 1922, U.S. airships were inflated with helium. In later years,the story ofRoma was largely forgotten.
