I've just now watched the entire video; what a hoot!
Recognitions galore! First image of the very first series Corvette, then Gentleman Jim Kimberly in the #5 Ferrari, noticed Briggs Cunningham and toward the very end, sports car enthusiast and TV personality Dave Garroway. That's exactly the kind of air base racing I did in the late 1950s in my little TR3, a very few years later than this video. Noticed a ton of Jaguar 120s, an OSCA MT4, the second red Ferrari 375 and the white 166 or 212, couple of Allards, likely Cadillac or Chrysler Hemi-powered, several Porsches and a ton of MGs, including the TF race winner.
How about the le Mans start, standing across the track from one's car till the flag, then running to the car, jump in and hope the thing starts. As always, at least one car doesn't. One thing to notice was the enormous difference in terminal speed between, say, the Ferraris and the MG's.
Then some of the non-race cars, an original series Corvette, a Kaiser-Darrin, a GM 'concept car' prtobably for a world's fair or something, and a (then) modern interpretation of Lincoln Continental.
WOW! Thanks for the memories!
