I had the good fortune of being at Edwards AFB for the first landing of Columbia and will never forget the thrill of being one of 250,000 cheering witnesses to that unforgettable event. Over the years I acquired every piece of Columbia memorabilia I could locate, much of it through a friend who works for NASA, and have continued to follow the "career" of the first functional shuttle. Today has not been a good day in my house. Rich Stephenson Calif.
