This Bell UH-1 Iroquois was sent to Vietnam in June 1967 and was stationed at An Son air base, where it logged over 1400 hours of combat flying time. More than 16,000 Hueys were produced, and during the Vietnam War the aircraft was used by all five branches of the United States Armed Forces. It was suited for missions ranging from troop transport to gunship operations, airborne battlefield command and control, troop insertion and extraction, medical evacuation, and search and rescue. The Huey was enormously successful in Vietnam because of its mix of cabin room, speed, lifting capacity, ruggedness, and service reliability. The UH-1 had an 850-shaft horsepower gas turbine engine and could be configured for up to fifteen seats or six stretchers and a medic. Vietnam veterans identify with the Huey's distinctive whop, whop, whop sound that often signaled lifesaving help. This Huey was restored by Indiana Air Search and Rescue, stationed at Metropolitan Airport in Indianapolis, Indiana.
