The Northrop C-19 Alpha was a series of three aircraft purchased from Northrop by the US Army Air Corps in 1931. They were slightly modified versions of the civil Northrop Alpha Type 2."The Complete Encyclopedia of World Aircraft" Editors: Paul Eden & Soph Moeng, (Amber Books Ltd. Bradley's Close, 74-77 White Lion Street, London, NI 9PF, 2002, ISBN 0-7607-3432-1), 1152 pp.] The major difference between the C-19s and the Alphas was that the civilian version carried a pilot and six passengers while the Army version carried a pilot and four passengers. One aircraft, the last of the three purchased, crashed between Richmond and Petersburg, Virginia on Sunday, March 19, 1933, killing its pilot and two passengers.Fact|date=September 2007 The other aircraft were used for several more years until being sent to training schools as subjects for maintenance and repair classes.
