Thanks Hamish!
Focke-Wulf FW190 just after returning from a test flight prior to Classic Fighters Air Show. Engine cooling fan blade failed and damaged the propellor preventing further flights at the show.
Proper rudder application would have prevented this tip stall if it had been used. In situations like this, applying opposite aileron actually causes the airplane to bank further into the tip stall. Opposite rudder would have prevented the snap roll and saved the airplane (but not the gear as that first bounce was really hard).
Planning ahead is always a very good idea when flying a twin engine airplane.
