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. == 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.
