General Background

In 1954 American Airlines was in the market for a 75 to 100 passenger for its short to medium range domestic routes. In response Lockheed developed the low wing L-188 Electra powered by four sleek turboprops instead of the usual large radial engines or jet turbines. The combination of engine and the Hamilton Standard propeller offered a much more reliable and fuel efficient aircraft that could travel at 375 mph for 2000 miles at an altitude of 20,000 – 25,000 feet. When production ended in 1961 there had been 170 Electras completed.
