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....
