- What's due to replace the shuttle in 2007 - the DC? I *sincerely* hope
- that the shuttle fleet won't be "run down" in anticipation of a 2007
- cut-off, regardless of whether or not a replacement is *actually*
- available by then! If NASA's historical record is anything to go by,
- a replacement due to enter service in 2007 is unlikely to be ready by
- then....
