astronaut and fox news contributor. tom, some amazing shots as we see the enterprise head toward intrepid to get lifted up there on the deck. tell us a little more about enterprise though. we know it never actually entered outer space. why is it, why is it such an important shuttle? >> well, jenna, it was the first space shuttle to be put together t was built out in palmdale, california. i got to see it when i was a air force cadet in the 1976. it took flight on five drops from the 747 to prove the space shuttle orbiter could land precisely when coming from space. those were crucial test flights, with pairs on board, astronauts on each one of those flights. jenna: without enterprise it would be unlikely we would have shuttles in outer space at this time? >> it would be tremendously difficult test flight to launch a shuttle not knowing whether it could make it back to a runway. that was entirely too risky.
