Eastern Air Lines received Electra 1037, registration NC14959, in mid-September 1935; as the company began to retire their fleet of Lockheed Electra aircraft for larger DC-2s and 3s, 1037 was sold to Boston & Maine Airways (which eventually became Northeast Airlines) and the registration was changed to NC243. The aircraft was then sold to R. P. M. Associates and from there, in the mid-1950s or early to mid-1960s, to Capitol Air Service, out of Manhattan, KS, where it received registration N5171N. Some sources state that it was then sold to Suburban Airways, based out of California, and then later was sold back to Capitol Air and others state that this particular aircraft never made it back to Capitol. It does appear, however, that Capitol Air Services, had at least two Electras total (that includes this aircraft). The Electra was eventually purchased and is currently on display at the Science Museum in Kensington, London, England. Electra 1037 which once bore registration NC14959 now hangs from the ceiling as if in flight with registration N5171N in small print on the tail of the aircraft.
