I googled the type and serial number together of a couple of interesting photos currently being auctioned and it brought up (via the Scramble database) an airshow at RAF Gaydon 1966...several other photos do 'corroborate' this result ...what was the 'Wedding Flight' noted on Canberra VX181's nose?
The image on my screen is not clear enough to see the dates. However I suspect the Canberra was used to get film of a royal wedding from the UK to one of the colonies. If you can see the dates, perhaps we can work out which wedding.
I think it says RECORD FLIGHT, not WEDDING FLIGHT.
VX181, the prototype PR.Mk.3, set up a new England to Australia record in January 1953. It left Heathrow on 27 January at 08.36; landed Fayid 13.05; took off Fayid 13.58; landed Karachi 17.29; took off Karachi 18.45; landed Singapore 01 22; took off Singapore 02.18; landed Darwin 06.44 (all times GMT). Total elapsed time was 22 hrs. 21.8 sec. for the 8,608 miles journey. The Canberra was piloted on F/Lt L. M. "Dick" Whittington; he had as navigator F/Lt J. A. Brown.
