Default Harlow PJC-2

https://en.wikipedia.org/wiki/Harlow_PJC-2

The Harlow PJC-2 was a 1930s American four-seat cabin monoplane, designed by Max
Harlow.

Max Harlow was an aeronautical engineer and instructor at the Pasadena Junior
College. Under his tutelage, the aircraft designated PJC-1 was designed and
built as a class project. The PJC-1 first flew on 14 September 1937 at Alhambra,
California but it crashed during an extended (more than six turn) spin test with
the center of gravity ballasted to the aft limit, as it was going through the
certification process—a problem generally laid at the feet the unusually
rigorous spin test requirement and the government test pilot, who bailed out of
the airplane after the spin "flattened out." The airplane struck the ground,
still in the "flat" (longitudinally level) attitude in a bean field near Mines
Field (now Los Angeles International Airport) with considerable damage; although
repairable, the PJC-1 was never returned to service. PJC students then built a
slightly modified airplane, which limited aileron travel with full aft-stick and
incorporated a slightly larger vertical stabilizer. This became the PJC-2 model,
serial number 1 certified by the FAA on 20 May 1938. It was one of the first, if
not the first, airplane designed and built in the U.S. with a stressed-skin
semi-monocoque structure—a revolutionary design feature for the time. Harlow saw
the potential and formed the Harlow Aircraft Company to build PJC-2 aircraft at
Alhambra Airport. Four aircraft were impressed into United States Army Air
Forces service with the designation UC-80 in 1942, and used by Civil Aeronautics
Administration inspectors after WW II.
