Woody, being "over there," you may not know what else Don did.
With no input from the PRA membership (indeed, without even announcing it in advance) Don went to the FAA as PRA's "representative" to get the existing gyro-training rules repealed. These rules had been put in place in the mid-60's. They allowed pilots to train in gyrogliders and to get a license based on demonstrated proficiency in gyrogliders. That's how everyone in the U.S. trained (yours truly included) until then. The PRA mag rubbed salt in the wound by printing an article after the deed was done, trumpeting the fine work done on our behalf in getting rid of this pesky rule.
There was a time gap between this charming little maneuver and the appearance of the experimental-training exemption. During that gap, the only way to be a legal gyro pilot was to take training in an Air & Space or McCulloch J-2. Don was at the time trying to put the Air & Space back into production. Coincidence?
You can argue the adequacy of gyrogliders as a training medium, but the misuse of the PRA name, without consultation with the members, for a project arguably in one's own interest was annoying at best.
