The review committee has left it to NASA to determine the scope of these alleged incidents.

That's what we want to do here at Johnson Space Center. I think what we have always brought to NASA and brought to the country is trying to push the boundaries, trying to go to the next level.

These incidents have left the officers numb.

I think of it as a good opportunity to let, in particular, school kids know that this job and other interesting jobs in science and engineering are open to anyone who works hard in school and gets a good education and studies math and science. And that it's not just for a select group of people.

I'll tell you, being involved in human space flight, it is an emotional endeavor. I think it brings in the highest highs and the lowest lows.

It was just very peaceful.
