Download -------------------------------------------------------------------------------- Fact Sheet Tools Printable Fact Sheet -------------------------------------------------------------------------------- After the start of World War II, the United States was in desperate need of many types of liaison, cargo and transport aircraft. To meet this immediate need, many civilian owned aircraft were impressed into service. On March 14, 1942, the Air Corps impressed nine Lockheed Model 12-A Electra Juniors and designated them as UC-40Ds (C-40D before 1943). Two more aircraft were impressed in late July 1942 bringing the total to eleven. Half the UC-40Ds were sent the Britain under a Lend-Lease agreement (British Serial Numbers LA619 to LA623). Three more of the planes were wrecked in accidents. One of the planes was destroyed at Key Field, Miss., when an aircraft tug backed into it. Another was written off after it was taxied into another plane on the ramp at Mitchel Field, N.Y. The last was wrecked after it crashed at Tampico, Mexico killing all aboard. Perhaps the most interesting use of a UC-40D was as an executive staff transport. One plane (S/N 42-38351) was delivered to the Iranian Mission on April 26, 1942, for use by Gen. Wheeler, U.S. Army. The plane was transferred to the Iraqi Mission on Jan. 1, 1945 and remained in service until 1946. The civilian Model 12-A Electra Juniors were generally similar to the C-40 and C-40As bought by the Army; however, most had the standard six passenger cabin on the commercial Model 12-A.
