[1] Harold Dale, an engineer at North American Aviation who had designed several homebuilt aircraft, teamed up with Edward Gagnier, a former North American engineer, to develop the Weejet.
[2] The Weejet was a two-seat side-by-side, mid-winged all-aluminum, retractable tricycle gear aircraft with a V-tail arrangement.
Air was fed to the engine through two triangular inlets mounted on the inboard wing roots.
The pilot bailed out safely and the prototype crashed after performing an unmanned inverted loop.
It was later found that the trim tab was set to full nose-down attitude during the test.
