When I was a child, my home had a 20-inch black-and-white
television. We could tune in about nine channels; the signal was free, and the
selection was more than enough. Today we have a 46-inch hi-def color flat
screen with access to hundreds of channels, but we only watch about six of
them. And I have to pay for it!
Back then, we looked forward to a future of supersonic flight.
This wonderful machine, which we knew as the SST, would be able to take us
anywhere on earth in just a couple of hours. But only about 20 were ever made,
and the entire fleet was grounded after only 27 years of service.
