We had one of our KC130T's on loan to Pax River do an inadvertent spin when the life raft deployed and lodged on the horizontal stabilizer. The crew on board learned several things. You can peg the airspeed indicator and bury the G meter during recovery and live to tell about it. The engineer who wasn't buckled in got to see all different aspects of the cockpit during the spin and recovery procedure. Thank goodness for T-34C spin recovery procedures. I was told they worked like a charm.
