I could say the same thing especially the DC-8/707, but I am still some years younger than you but I was fortunate to travel to all kind of nice places when I was younger, I had tons of cockpit flight with Aerolineas Argentinas ( my dad used to fly for them ) and then there were tons of photo opportunities at SJU, SDQ, CCS, MIA, LAX, SFO, PMI, LAS, etc......I was out on the ramp in FRA visiiting the B74F a couple of times. I missed all these as I always was into airplanes but had no relationship to photography and I have seen and flown many many nice airliners over the years.
Somehow this makes me a little mad, but there is nothing you can do.
No too long ago, probably 2 years ago and then I just had a point of shot camera, I was invited by AA BOS to take a look at their first 777 visiting. Hmmmm the photos turned out not to good.......but anyway....
Normally I prefer "heavies" but with the correct light and angle you can create some dramatic photo even with a narrowbody, i.e 737, MD-88, Canadair etc....
this time from FRA
