I just watched the Space Shuttle Discovery launch on HDNet (Nothing like watching and listening to the HD launch) and it appeared flawless.  Excalibur wishes best of luck to Colonel Pam Melroy (USAF Ret.) and her crew.  I knew Pam years ago when we were stationed at Barksdale together, she flew KC-10’s and I flew B-52’s.  Their mission is to deliver the Harmony Module to the International Space Station, one of our advisor’s is Bill “Shep” Shepherd, first commander of “Alpha” the name of the ISS.  Godspeed and our best wishes for a successful mission!
