At some point after the STS-107 failure, Johnson Space Center posted a lot of valuable material online that hadn't been publicly available before. Especially the STS Generic Flight Rules, which used to have a banner in it POSTING ON ANY ELECTRONIC FORUM IS EXPRESSLY FORBIDDEN.
The Flight Data File page is now wearing the abandonware banner like the late lamented spaceflight.nasa.gov. Hopefully these great resources aren't going down the memory hole.
Now it appears that JSC's web site is being assimilated into the Borg-like and dumbed-down mass of "nasa.gov" Are the flight rules still available? They used to be at http://www.jsc.nasa.gov/news/columbia/fr_generic.pdf
