accident board for neil armstrong's flying simulator for the lunar module and trying to determine what had happened. it was very obvious the machine itself had failed. >> okay. wally, what would you think looking back over it -- you flew mercury, gemini and apollo. >> uh-huh. >> what do you think your biggest contribution was to the space program? >> i used the word earlier. commitment. i made a commitment to do the things i could do within the time frame i was willing to do it, which is almost ten years to the day. april to july, really, ten years of doing what i thought was appropriate. they got a man into space to make a man perform in space and to make the prelude of going to the moon and back. all those things were done. i thought i had a good time. >> there are some things i'm sure you look back on and say, that was a key to the space program. i really did something there as compared to just doing the job that you had to do. >> i would say i enjoyed gemini fully. i did apollo. approxima five hours in space, i was anxious to go up there for 9.3 days. i was bored tears up there for 11 days. i mean bored. fighter pilots like to fly for an hour, hour and a half,
