The McDonnell Doodlebug is a light aircraft that was built to win a 1927 safety contest by McDonnell Aircraft founder, James Smith McDonnell.

Design and development

The Doodlebug was built in response to a 1927 safety contest sponsored by the Daniel Guggenhiem Fund for the Promotion of Aeronautics with a prize of $100,000. The aircraft was built at the Hamilton Aero Manufacturing factory in Milwaukee, Wisconsin. [1] l The Doodlebug is a tandem-seat low wing taildragger with a fabric covered steel tube fuselage. The landing gear featured widely spaced main wheels. The wings featured full-length leading-edge slats.

Operational history

The Doodlebug was produced too late to compete, but was granted an exemption. The aircraft's tail folded upward in initial demonstrations at Mitchel Field in New York, and allowed more extensions to repair damages. [2] After a forced landing due to engine failure, the Doodlebug missed the opportunity to be judged in the competition. The winner of the competition was a Curtiss Tanager. The forced landing caused McDonnell a back injury, but he drove the aircraft to demonstrate in various air shows throughout the start of the Great Depression. [3] [4] In 1931 the Doodlebug was sold to the National Advisory Committee for Aeronautics (NACA) as a demonstrator for leading edge slats. [1]

Boeing YC-14 Military transport aircraft prototype by Boeing

The Boeing YC-14 is a twinjet short take-off and landing (STOL) tactical military transport aircraft. It was Boeing's entrant into the United States Air Force's Advanced Medium STOL Transport (AMST) competition, which aimed to replace the Lockheed C-130 Hercules as the USAF's standard STOL tactical transport. Although both the YC-14 and the competing McDonnell Douglas YC-15 were successful, neither aircraft entered production. The AMST project was ended in 1979 and replaced by the C-X program.

McDonnell Douglas DC-9 Twin-engine, single-aisle jet airliner produced 1965-1982

The McDonnell Douglas DC-9 is a single-aisle airliner designed by the Douglas Aircraft Company.
