How did you fly from Singapore to HK?
Would you believe in a Bristol Freighter of 41 Sqn RNZAF! Not one of the most comfortable trips I've ever made, but the high point was a refuelling stop at Qui Nohn in Vietnam, a couple of weeks before the 1968 Tet offensive. Never seen so many helicopters (mainly Hueys) in one place in my life, before or since.
