The L-5 "Sentinel" began life as the pre-war Stinson model 105. The model 105
was nicknamed the "Voyager", built by the Stinson division of Consolidated
Vultee.  . When the war broke out, the "Voyager" was pressed into service as a
liason aircraft.  It also flew in the artillery spotter role and as an air
ambulance. The military L-5's had their fuselages structurally reinforced and
lengthened to accommodate two litter patients.  The L-5 was powered by a 190 hp
Lycoming O-435-1 engine.  Three versions were produced for the US Army Air
Force; the L-5 and L-5A standard two-seat short-range aircraft, the latter being
identical to the L-5 except for having a 24 volt electrical system, and the
L-5B, or Sentinel II, was adapted to carry a stretcher or light cargo.

Capable of operating from forward unimproved airstrips, the L-5 "Sentinel"
delivered information and needed supplies to the front line troops On the return
trip, she would evacuate the badly wounded soldiers to rear area field hospitals
for medical attention.

Over 3,000 L-5s were constructed and served with distinction in Europe and in
the Pacific.

This L-5 aircraft is serial number FAA # 63085, and arrived at the museum in
November, 1982. This aircraft is on loan from the USAF.
