Lockheed Model 18 (R5O-5) Lodestar
The Model 18 is a slightly enlarged Model 14 Super Electra designed to compete with the Douglas DC-3. While the Lodestar was relatively successful in airline service it never quite met the expectation placed on it. In part this was due to the U.S. military impressing many of the aircraft into military service with the outbreak of World War II. The R5O-5 was identical to the civil version of the aircraft and were used as 14-seat transports by the U. S. Navy. After the war, most of these aircraft found their way back to civilian hands.
