that led up to the first flight in 1981 when we flew columbia in space for the first time. the way we do this, we have very smart people in the country that can design anything if we put our minds to it and we can make stuff like this work. it really is a progression, i think that is a very good point. not like you started out doing this first time-out. no, in any flight test program for any new airplane or any new spacecraft you use a build up approach. do the stuff that is easier and safer first, you gain confidence over time, and eventually you put a crew like john young and robert krippen in columbia and blast them off in space for a couple days. so we continue to watch this 747 with the enterprise on top, and it s making its flight over new york city, eventually make its way to jfk where in 15 or
