- There was a movie made on this theme at least 10 years ago. The US transport
- system was by emag, and after a war (?) people were rediscovering the
- connections. Also perhaps a story by Clark? One idea is to have the tube
- drop, so that the train falls down deep into the earth and comes back up at the
- destination. Only a little extra shove would be needed to assure that it got
- to the same level, more if the destination is at higher potential. It would be
- pretty bad if something went wrong, and one fell back and kept swinging
- though... :-)

- The nice thing about your proposed weightless facility is that it would be more
- accessable than orbit. Also, you could have any mass (whole cities??) in the
- orbit.
