The L-5 was the military version of the commercial Stinson 105 Voyager. Six Voyagers were purchased by the AAF in 1941 as YO-54s for testing, and quantity orders for Sentinels began in 1942, first as O-62s before the designation was changed to "L" for liaison in April 1942. Between 1942-5, the AAF ordered 3,590 L-5s, making it the second most widely used AAF liaison aircraft.
The unarmed L-5 with its short field takeoff and landing capability was used for reconnaissance, removing litter patients from front line areas, delivering supplies to isolated units, laying communications wire, spotting enemy targets for attack aircraft, transporting personnel, rescuing Allied personnel in remote areas and even as a light bomber. In Asia and the Pacific, L-5s remained in service with USAF units as late as 1955.
The Alamo Liaison Squadron's L-5 Sentinel was built in ambulance configuration and is cabable of accomadating a stretcher case in the rear hatch.
