Years ago I got carried away trying to burst balloons in a Tiger Moth and went into an incipient spin at about 1500'. Fortunately I was an experienced glider pilot in those days and was used to being on the edge during turbulent soaring and managed to recover after about half a turn and only lost 200' or so. The instructor (safety pilot)in the front didn't say anything so I'm not sure he realised what was going on. Although I hit one of two balloons, I never managed to burst one.
This was all part of an annual club competition which also involved dropping flour bags on a target followed by a spot landing. Can't say I ever did particularly well.
