I was lucky - one engine fire that went out with the extinguisher and two
false indications (but only realised once on the ground).

I had a similar experience as ground crew on a 37 Sqn. Mk2 returning to K´sar from Majunga in 1966. The fire was extinguished successfully but the damage caused prevented the prop from being feathered. We eventually landed safely at Embakasi, Nairobi.
My grateful thanks to the captain, Flt. Lt. Nick Nicholls and his crew for that.
