It is to my lasting regret that in 1978 I had the opportunity of buying a ticket on BA to Brunei and flying on a VC10 and to then connect to Kuching, or flying with SIA to Singapore on a B747 and then on to Kuching. I took the latter and of course have never been on a VC10. Sods law that one. However one consolation is that I was allowed on the flight deck on the SIA aircraft on the Orly to Dubai leg. Fantastic memory that and of course now impossible. But I still regret not taking the BA flight (and I never regret not taking BA flights in economy!).
