Once did a spin in the glider whilst doing a test flight, with a Phantom pilot as ballast. Only looking to do an incipient, the type are very reluctant to spin, had only ever got a spiral dive before. However we were both lightweight and the cg was just right, I yelled 'yippee a spin'. the Phantom jockey just went quiet. He later said if they departed below 10,000' (I think that was the figure he said) their rules were to punch out, we were below 1000'!
