First flown in 1957, it was the first large turboprop airliner built in the United States. \u00a0 \nWith its unique high power-to-weight ratio, huge propellers and very short wings (resulting in the majority of the wingspan being enveloped in propwash), large Fowler flaps which significantly increased effective wing area when extended, and four-engined design, the airplane had airfield performance capabilities unmatched by many jet transport aircraft even today\u2014particularly on short runways and high field elevations. \u00a0 \nJet airliners soon supplanted turboprops for many purposes, and many Electras were modified as freighters. Some Electras are still being used in various roles into the 21st century. The airframe was also used as the basis for the much more successful Lockheed P-3 Orion maritime patrol aircraft. \u00a0 \nFor the full Electra story, click here.
