Ever since aircraft changed the scope of the First World War, flight became both a passion and business in Riverside. Early barnstormers needed places to park, refuel and service their aircraft, so airports started popping up. Alessandro Field became March Field in 1918. By World War II, seventy-five thousand troops were deployed at March. Today's March Joint Air Reserve Base has been a vital wartime training and relay installation and a sentinel of peacetime. In 1925, Roman Warren, known as the "Cowboy Aviator," established Riverside Airport, which later became Flabob Airport. Take to the air with authors Marge and Tony Bitetti as they trace Greater Riverside's history of flight—from Banning, Corona and Riverside Municipal Airports to Perris Airport, Skylark Field and others.
