Pilots take no special joy in walking: pilots like flying.

History will remember the twentieth century for two technological developments: atomic energy and space flight.

No matter when you had been to this spot before, a thousand years ago or a hundred thousand years ago, or if you came back to it a million years from now, you would see some different things each time, but the scene would be generally the same.

We had hundreds of thousands of people all dedicated to doing the perfect job, and I think they did about as well as anyone could ever have expected.

I was elated, ecstatic and extremely surprised that we were successful.

It doesn't sound like there was time for the word to be there. On the other hand, I didn't intentionally make an inane statement... certainly the 'a' was intended, because that's the only way the statement makes any sense.

I can honestly say - and it's a big surprise to me - that I have never had a dream about being on the moon.
