Message-ID: Date: 9 Jan 90 19:12:33 GMT Sender: usenet@icad.COM Distribution: usa Organization: ICAD Inc., Cambridge, MA Lines: 8 I used to know this, but a friend asked me recently, and I can't remember. The question is: Why does the shuttle roll on takeoff? If there is a simple answer, like, "to get into orbit upside-down" then please state why this is necessary. Thanks. --J Gregory
