The aircraft is unusual in that primary gliders went out of fashion in the 1930s and few have been built since.

[1][2][3] Jongblood designed and built this primary glider in 1966, with assistance from Hugh Knoop.

The glider has a detachable pod to cover the pilot or can be flown open cockpit.

It had flown a single three-hour flight and had recorded a height gain of 8,000 ft (2,438 m).

In May 2011 it was still on the Federal Aviation Administration registry listings, although its registration had expired on 31 March 2011.
