Twice on planes

This coincidence occurred in the early 1970s. Following a business visit to Denmark I boarded a British European Airways Trident at Copenhagen Airport. The older Tridents had two rows of seats facing each other halfway down the cabin. As I was about sit on one of them I realised that sitting opposite me was my sailing friend Bill. After several G & Ts we were met at Heathrow by our wives Susan and Jenny who had once been my girlfriend. Six months later I was on a business trip to Australia. I boarded a flight from Perth to Adelaide and as I sat down I saw someone who looked like Bill sitting in a first class seat at the front of the airplane. As soon as the seat belt sign was off I walked forward and to my amazement it was Bobby with Jenny sitting next to him. Later we stayed in the same hotel in Adelaide.
