After the Hiller 12E (56 hours) in the RN it was on to the Whirlwind HAR Mk3 and HAS Mk7 (42 hours). Wings awarded after 98 hours helicopter time in Feb '65 before AFT and OFT on the Wessex. How times change! Never flew the Whirlwind again. Seem to remember with the Mk3 the Wright Cyclone had to be shut down to do a practice engine off landing otherwise the throttle opened when you raised the collective to cushion the landing. That made you very sure you were going to reach the spot before you shut it down.
I recognise some of the names in the posts above...especially Don Sissons as the CAA trapper who always put the fear of God into me in civvy life when he did my Bell 212 and Bo105 initial type instrument ratings.
