This is how long it would take (add to the shipping date) if they go for the MAF option, as opposed to KSC.
Yes, that is a worry about STS 115 as that has it's own support mission requirement with STS-301. No 301 and no STS-115.
It would also seem that the "penciled in" flight of STS-116 could be pushed back to 2007 if it gets much tighter with the contingency days. Any word if the FAWG has or will put out a manifest soon?
