Brian,
Thanks very much for adding to the wonderful memories. My first ever visit was in 1960 with the school and from then on, I was 'hooked'. Indeed the atmosphere on the roof gardens of the Queens Building and Europa Building was magical. The spluttering pistons engines, the whistling turboprop Viscounts mixed in with the 707s and DC-8s provided the 'background music', whilst the commentator announced information about arrivals and departures with Glen Miller music in between! You could never recreate such a mix, but I aim to do just that on my 1/400 scale model with all those background sounds! It'll be the nearest thing I can get to bottling nostalgia!
I've just checked out the Air-Britain site and what an incredible collection of photos you have uploaded. Did you ever take any in colour?
