Here are the very poor quality photos I took in about 1970 as an enthusiastic nine year-old lad with my Kodak Instamatic of one of those early morning Breguet 763 Air France cargo flights mentioned above, preparing for departure from Heathrow. This one is F-BASN.
We used to regularly see those flights over our house (in Egham) and my father (a BOAC engineer) had a chat with the Air France engineers and arranged for the family to go to Heathrow early one morning to have a look over the aircraft before departure.
I'll always remember the wonderful sound as those Breguets flew over.
