Yes, it's been done before. There's a great story about the Schweizer 1-35

flight test with one tank full and the other empty. Bernie Carras (who

the spin to break. It finally recovered fairly low, and he landed the

plane. He gave the plane a few extra kicks once he got out, just for

good measure!

I doubt if my father ever kicked the prototype 1-35.

The problem was not with spinning the sailplane with water in one wing, that was ok, but when it was in a tail heavy flat spin with a lot of jettisonable lead at the tail that did not jettison as it should have, but finally did.
