Quotes 

• Christopher Kraft : I saw a lot of rockets launched. I'd say that somewhere between 30 and 40 percent of them failed. A lot of them came up off the pad and went the opposite direction. Some of them got halfway off the pad and blew up, some of them got to 10 000 feet and turned the other way and blew up.

  John Glenn : We're looking at this thing and we're looking at each other and deciding we want to go back and talk to the engineers a little more before we go further.
