I fondly remember this show, Dick Cavet did a great job hosting, with his signature monotone voice. "Wheels, Wings, and Whistles" is the episode I remember most. For years I had it on VHS, sadly the tape wore out. HBO can feel free to delete some of the bad shows they air, and replace them with their old material. Or offer this on DVD. I found the show to be informative, well planned and an excellent source of historical material. This episode, for which I believe was number 3, covered the history of transportation in the US, from the Ford Model T to the massive Boeing 747, and from the Titanic, to the Space Shuttle Challenger.
