Reading the video comments, I see that someone long ago beat me to the butt scratching comment about 0:42. That we turned our backs on the idea of the SST, and more efficient means of ground transportation over the years is not just unfortunate, but perhaps a detriment to America as a whole. Consider how high speed rail is doing in the U.S., as well.
Our future passed is a lot like "Our New York" in Charles Carpentier's Flight One. It would have been wonderful, but we won't be there...
