Lockheed Air Express
The Lockheed Air Express was the second aircraft design created by the Lockheed Aircraft Company after its founding in 1927; the type first flew in April 1928.[1]
Description
The Air Express design incorporated the original fuselage of the Vega, but in order to meet the requirements of Western Air Express, the wing was raised to a parasol configuration above the fuselage and the cockpit was moved behind the wing, while a more powerful Pratt & Whitney Wasp engine was fitted to ease operations over the Sierra Nevada mountains.[2] The design was a commercial success for the company although only seven were built, plus one Air Express Special.
No Air Expresses have survived to the present day. One, registered NR3057, was flown by Roscoe Turner.
