Spinning a Large Aircraft
The largest aircraft I know of to be spun and sucessfully recovered was a RAAF C130A (A97-207) which was unintentionally spun during a stall demonstration during a training flight. The aircraft was, fortunately, high enough for a recovery to be achieved. The aircraft was damaged structurally but was returned to service after repairs. The incident resulted in a modification to the stall practice procedure in that a minimum of 1000 "/lbs of torque was to be set on all engines prior to the stall, so as to preculde any NTS (Negative Torque System) action during the procedure.
