Design and Development
The prototype of the Lockheed Model 18, which first flew in 1939, was constructed from one of a batch of Lockheed Model 14 Super Electras which had been returned to the manufacturer by Northwest Airlines after a series of crashes of Model 14s. The fuselage was lengthened by 5 ft (1.5 m), enabling the fitting of two more rows of seats and hopefully making the aircraft more economical to operate. However, most US airlines were by then committed to purchasing the Douglas DC-3, and Lockheed found the Lodestar difficult to sell at home.
A total of 625 Lodestars of all variants were built.

Famous quotes containing the words design and/or development:
“Westerners inherit
A design for living
Deeper into matter—
Not without due patter
Of a great misgiving.”
—Robert Frost (1874–1963)
“The proper aim of education is to promote significant learning. Significant learning entails development. Development means successively asking broader and deeper questions of the relationship between oneself and the world. This is as true for first graders as graduate students, for fledging artists as graying accountants.”
—Laurent A. Daloz (20th century)
