There used to be a flying car marketed back when I was in high school. It was similar in concept to modern versions I've seen lately, a 4-seater whose prop disengaged so the engine could drive it like an automobile. The wings detached and could be towed behind the cabin like a small trailer, so you could land at an airport, convert to car mode, and drive to your ground destination.

You may be thinking of ljk, who used to post here until the politics drove him off. In fact, he was the guy who first turned me on to the Zone. He and I correspond occasionally (he published my first two articles in his magazine back in 1995!) and I still get his email newsletter.

I've lost his address, but next time I get his bulletin I'll forward your question to him.
