 was not very well put together, and that accident caused a lot of examination, a lot of improvements, and probably is the only reason we didn't lose a crew out by the moon later on. It also gave time for Grumman Aerospace up in New York to get the lunar module finished because it was running behind schedule. So at the end of the day, although it was a horrible, horrible tragedy, it actually, in some ways, worked to the advantage of the lunar landing program. We lost three great astronauts that day.
