John, your photos are just stunning.
It seems many many years ago when I used to love watching BOAC 707s, VC10s, and then 747s dropping into Manchester Airport when I lived near there as a kid. And also things like British Caledonian 707s, TWA and Pan Am 707s, Spantax CV990s, Air Spain DC-8s, Laker DC-10s, Wardair 747s, Trans Europa Caravelle's, BEA Viscounts plus so much more. Happy days!!
I used to have a Canon AE1 (I think?) and loved going to airports and airshows. Got albums full of 6 x 4's, but I envy the clarity obtained by John in his exceptional photos. Favourite places were Hotel Emmantina at Athens with its rooftop area and pool, Miami International, and Frankfurt. But I also loved Fairford Air Show to see the fast jets.
Nowadays I collect diecast 1/400 model airliners and 1/72 WW2 planes as a reminder of those great days- just love the Spitfire and Hurricane, and those German Heinkel's, Stuka's and ME109's. Just recently I obtained a Defiant, built a mile from where I live now on the outskirts of Wolverhampton by Bolton-Paul.
