The Lockheed L-188 Electra prop-jet airplanes were high tech in the 50s… but then the planes started crashing

First entering service with Eastern Air Lines in 1959, the Lockheed L-188 Electra was a leap forward in airline technology when it appeared.

Selling well right out of the box (as the below ad indicates — 144 initial orders) the Electra was bound to be an overnight success. And it was — for a time.

Unfortunately, a design defect with the engine mounts caused an oscillation to be transmitted from the outboard engines to the wings, vibrating the wings in a severe up-and-down motion — until the wings would tear right off the plane.

Three Electras were lost in this way in the fourteen months between February 1959 and March 1960.

While the defect was tracked down and remedied in existing planes, and all new ones were built with the modifications, only a total of 170 Electras ended up being manufactured.

Despite the stigma from the early failures, Electras went on to serve long-lasting careers as freighters. Moreover, the military version — the P3 Orion — ended up selling over 700 aircraft, many of which were still in operation more than 50 years after their original appearance.

The Lockheed L-188 Electra makes her debut - a leap forward in airline technology (1958)


Lockheed Electra (1958)

The only practical, economically sound air transportation machine for “short-to-medium haul” airline routes!

“Short-to-medium haul” What is it?

Route patterns divide into “long-haul,” “medium-haul,” and “short-haul”… each with different characteristics… each requiring a specialized air transport to fit its needs. Short and long-haul characteristics and the kind of machine needed are most clearly defined. Medium-haul is between the two, and is less clearly definable.

Route definition

(1) Long-haul: a pattern of long, non-stop flights between big cities with big airports — generating heavy traffic.

(2) Short-to-medium haul: involves a varied pattern with many intermediate stops — with lower flying altitudes for shorter periods – and between large, medium and small cities… some with small airports and with traffic varying from very heavy to very thin.

Transport requirement

(1) Requires the large turbo-jet powered airplane, flying at high cruise speeds and high altitudes for long periods.

(2) Requires a highly specialized, flexible machine of just the right size and carefully tailored to fit “short-to-medium” haul needs. Emphasis must be on economics since airline unit operating costs are inherently higher in this area.

Since 35% to 65% of air traffic travels on “short-to-medium” haul routes, profit or loss on this portion of the system determines airline financial success.

Lockheed Electra…

The Electra is the only practical air transport in the market or under development, explicitly designed from the very start to fit the particular functional needs of “short-to-medium haul.” It was designed and produced by the greatest team in aviation history: Aircraft by Lockheed (California Division) / Power by General Motors (Allison Division)

This outstanding team, by employing the most advanced aircraft and turbine power technology in the proper combination for the required job in the turbine age, developed and produced the Electra.

Results that solve the short-to-medium haul problem for today and tomorrow

Realistic economies: Profitability under today’s and tomorrow’s operating conditions. No unknowns!

Dependable passenger appeal: Quiet, vibration free. Shortest elapsed trip time and most frequent schedules with all-weather dependability. Not just novelty appeal!

Practical operational performance: For “many-stop” schedules under today’s air traffic control conditions. No unpleasant surprises!

Realistically achievable: Highest utilization, shortest ground time with practical load factors on “many-stop” schedules. The tool fitted to the job!
