Found this clip out of sheer luck recently which was a promo from Pan Am back in 1958 called "Six and a half Magic Hours" featuring their new 707 Jet service to London from New York. It's a great ~12 min clip and shows the glory days of flying. Clip also has info on the new 'soon to be completed' Pan Am terminal at JFK (then Idyllwild) and on board service. Great shots of air to air filming of the 707 in flight.
I found I had problems on the 'stream' function, (it ran 'fast' and garbled) but instead opted to download it. I downloaded the 256K mpeg4 file (just a random choice) and opened it while in Apple Quicktime (windows). I guess you'll have to see which one works for you.
Anyway, for the Pan Am lover of yesteryear. Enjoy!
