Being rostered to operate as the sole cabin crew on BOAC 707 Cargo flights had some benefits including the Hong Kong ‘Checkerboard’ landings the first of which I experienced in October 1970. We were followed in by an RAF Vulcan which had impressed our flight crew with a very rapid descent I guess those big air brakes were very effective. Never saw another Vulcan out there again although they appeared in Nairobi occasionally. Often wondered if Hong Kong was a regular trip for the Vulcan crews?
