A Brief History Of The Stearman Speedmail

The Stearman M-2 Speedmail was an American mail-carrier biplane produced in 1928. It was a single seater, with two large cargo compartments in place of a front cockpit.

Lloyd Stearman and Mac Short, (Stearmans V.P. of engineering), designed the Speedmail to meet the requirements of Varney Air Lines, which needed a new mail carrier with greater capacity to fly Air Mail routes it acquired from the U.S. Postal service.

The result was a sturdy and capable aircraft with good flying characteristics and a large cargo capacity which met or exceeded Varney Air Lines’ requirements.
