Although I was only 10 at the time, I remember spending most of the day running up-and-down the runway in a cut-down open top red jeep driven by a guy named 'Andy' (the CD?) chasing Free Flights. Myself and another kid had been flown to Millville from Medford Lakes because we'd won prizes in a kids' solid scale model contest. It was my first exposure to powered models.
In the afternoon we were awed by the "Beauty" (CL Scale) event. Main memories are of an F2G Corsair Thompson Trophy racer, a couple of then-new Sterling SE-5s and Wacos, a gorgeous Stinson Station Wagon (Cleveland kit?) and a tiny Speedee-Bilt Long Midget (metallic blue) with a K&B .020 -- which everyone treated as a joke.
The only "stunting" I recall seeing was the attempt by the Sterling designs to fly loops....which ended in disaster.
We flew back to Medford Lakes in late afternoon....and things just haven't been the same since.
That trip, by the way, was in a Stinson Voyager owned by Everett N. Angus, AMA President 1948. It was only recently that I learned that Mr. Angus was Jim Vornholt's grandfather.
Small world!
