MIke, what a great mystery.

Are the flaps of the fowler variety? If so "Wealthy industrialist and
gliding enthusiast, Hugh Keartland sponsored the SA entry into the
World Gliding Championships in Marfa in 1970 and a second BJ4 was
built by Pat in record time. The two gliders, renamed the BJ4A and
BJ4B, were shipped to the US to be flown by Pat and Bomber Jackson.
Unfortunately weather conditions were poor and the craft
disappointed." In fact one was damaged in the WGC. The hitch is I
think the BJ series had a "T" or conventional tail. Great stuff.



Hi John

BJ4 had conventional tail, and both are a accounted for - I've "met"
both of them - even helped rig one for a display. If you look in the
soaring encyclopaedia for the term heavy wings it says cf BJ4...
