09/21/2003. Remarks by Johan Visschedijk: "In the early fifties Harold Dale played with the idea to design the ideal jet trainer: seating trainee and instructor side-by-side in front of the wing for clear visibility all around. It should have a slow landing speed and a comfortable cruising speed of 350 mph. The plane Harold had in mind was a mid-wing cantilever monoplane of aluminium alloy structure, with slotted flaps, leading edge intake ducts, semi-monocoque fuselage, upwards opening doors, butterfly tail unit and retractable tricycle landing gear.

Harold Dale was a project engineer with North American working on the F-100, so his ideal plane had to be designed in the spare time. He had assistance from his wife Eleanor who also had an engineering degree, handling much of the mathematics, administration, etc.

Harold and Eleanor Dale

The name chosen was the Wee Jet 880 (We = Harold and Eleanor), the 880 referred to the power of the license-built Turboméca Marboré II engine of 880 lb thrust.

In February 1952 Dale Air-Engineering (Torrance, California) and the Wee Jet 880 were official registered and the first material was submitted to the CAA West Region Administration. It was the first jet aircraft in the small plane field submitted to the CAA, who followed every phase of the two and a half years of design and evaluated all data during development.

In 1954 a local aircraft parts manufacturer (Carma Manufacturing Co) heard of the design and got involved in the project in two ways: he supplied the hydraulic shock absorber struts and offered to built the aircraft in his plant in Tucson, Arizona. Now it became feasible to produce and market the aircraft.

Construction started at Tucson in the second half of 1954 and five people worked one and a half years on it.

The prototype (N8209H) conducted its 20 minutes first flight on Good Friday March 30, 1956, with Harold Dale at the controls.

During the following weeks further test flights were made by another pilot, except for the spin tests, these were performed by USAF-pilot Doneby; the aircraft handled and performed well.

During 1956 the US Navy had become interested in jet trainers and the Wee Jet was to be in their evaluation. Therefore all data had to be available before the end of the month and the aircraft was to be flown to Patuxtent, Maryland on April 29. On April 28 1956 disaster struck: during the final spin test the pilot inadvertently activated the trim tab into full nose-down position. The pilot lost control while trying to recover and had to bail out, the aircraft crashed and burned. Later data was found thrown clear of the wreckage, showing the spin tests were a complete success.

All following data was issued on April 25, 1956 in a proposal to the US Navy for the production version. The designation was Carma WEEJET TRAINER."
