I thought I just saw an article that said that NASA was not going to do anymore nighttime shuttle launches because they want to keep a close eye on the foam insulation on the external fuel tank and that it would be difficult (impossible???) to do that a night.
We saw the July 4th launch of the shuttle from EPCOT this summer. It was an awesome sight. I'll be arriving in Orlando on the morning of December 7th. It would be great to see another shuttle launch (assuming that they don't move it back to the 6th).
