I'm not going to recall this precisely, but there was a famous live TV interview, where just seconds before lift off, Walter Cronkite was told he could ask (I beleive it was John Glenn) just one quick question...
So, Cronkite asked, "Are you nervous?"
The astronaut replied, "I'm sitting 387 feet in the air, atop the explosive power of 3 million pounds of TNT, in a craft assembled of 670,843 parts, each of which was furnished by the lowest of three bidders... yes, sir, I'm pretty nervous..."
