Quite right of course, SASless - but in my 6 years on Wessex vs 9 years on Chinook, I never heard of any crew wrecking a Vertol (OK, Boeing..) combiner whereas the one in the Wessex (and Lynx..) positively invited error from distracted aircrew. I wouldn't mind betting that the HYD systems on the Vertol design both carried on working in the event of a double-donk stop, unlike the Wessex.
