Roma was an Italian-built semi-rigid airship, designated by its designer as the Model T-34. Purchased by the United States from the Italian government in 1921, Roma was operated by the United States Army Air Service from November 1921 to February 21, 1922, when it crashed in Norfolk, Virginia, killing 34 people aboard, with 9 survivors. As a result of this accident, Roma was the last hydrogen inflated airship flown by the US military; all subsequent airships were inflated with helium.
