one of the interesting tidbits gleaned was that Carl Goldberg credited the introduction of the Shoestring as having saved his company from folding. Such was the power of C/L in that time.

You are exactly correct in this. If you read Dave Thornburg's book, "Do You Speak Model Airplane", Dave credits control line with saving the hobby industry in post-war America. R/C for the common guy was a long way off in the late forties and early fifties, and control line was sort of a bridge from the old pre-war free flight era to the dawning of main stream R/C modeling in the late 1970's. The growing suburbia in most major cities was making free flights sites hard to find, and control line could be flown in lots of sites in most cities, and in order to fly R/C one had to have an FCC techinicans license in the arly days. I started to fly R/C sailplanes in 1975 and I had to apply for a non-voice FCC license that cost 25 bucks at that time, and when the CB craze hit about the same time, I had to get a separate license for CB. Now you can buy R/C flying toys at just about every drug store, gas station, and mall in America!
The times sure have changed!!!
