They appear to have the 'go ahead' for launch.
American power baby!
I watched the launch on NASA TV; creat sight to behold. Every launch makes me tip my hat to the scores of engineers and aerospace technicians who created that machine. I want to pat the back of every man and woman behind the shuttle and say, "Damn fine work!"
'Tis a pity that that the first one did not launch early enough to save and restore Skylab.
