There is a wonderful story (possibly apocryphal) of a Vulcan doing a wheels-down approach to a flat topped Australian warship which was anchored and minding its own business in Penang Harbour, this would have been in the late 60s, the Vulcan fleet would regularly send one of their number from Singapore to Butterworth for a couple of days to show the flag.
In this case the Penang approach would have been quite worrying to the crew sunning themselves on deck.
