- No, I disagree here. NASA has never had four working shuttles in
- service at the same time (not even late '85, Discovery was down
- for Vandenberg preps) so we cannot yet say Shuttle is flying at
- its peak. Near yes, if you consider three or four more flights
- per year 'near'. I think NASA could easily handle 12 flights
- per year, but politics has forced them to cut down to eight.
- In 1992, all four orbiters flew twice, but Discovery was offline
- from February to November, Columbia offline from January to May,
- and Atlantis offline from August to December. Take away those
- downtime periods and you can add three more flights. This is all
- moot, since NASA apparently does not want to push its luck prior
- to SSF assembly, but it does show that the launch rate is lower
- than it could be.

- Which is probably why Boeing has not taken the plunge into the
- SST airliner or a 747 successor. This cost seems to effect just
- about everything except the DC series.
