I too have fond memories of my one and only flight in a BEA Vanguard as a lad in May of 1968......G-APEO London to Amsterdam
Still have the "Flight Bulletin Form" which was passed around the cabin.
Captain Webster, First Steward Mr Lavers, Altitude 15000ft at 400 mph,
passing Clacton 20 minutes after take off, arriving AMS 50 minutes after take off.
I remember entering the aircraft and taking the first window seat on the left side of the aircraft which was an aft facing club style arrangement with a table set up between us and the second row which was forward facing.
Great view of those Tynes through those magnificent huge oval windows and it was a clear blue mid morning flight so great view of the channel and the tulip fields as we came into AMS
