It's nice to know I wasted a few years of my life on a mistake. What a bonehead statement!
This is possibly true for the Space Station, especially after it morphed from the original Freedom design to "Ralpha" (Russia + Alpha) and moved from 28 deg to 51.5 deg to suit Russia, but not shuttle. We learned everything we know about reusable space propulsion hardware from shuttle. That information will be priceless if we ever get to critical mass in repeated flights to orbit.
If I know the government, they'll destroy that information.
A 28 degree orbit would have left it unserviceable by Soyuz and Progress launched from Baikonur. It would have burned up on re-entry many years ago like Skylab and Mir during those long periods when the Shuttle was grounded for one reason or another and couldn't resupply it or boost it to a higher orbit. I don't think that's what you want is it?
