It was especially hard for me, as a professional pilot. In all of my years of flying - including combat in Korea - this was the first time that my aircraft and I had not come back together. In my entire career as a pilot, 'Liberty Bell' was the first thing I had ever lost.

The flight crew for the orbital mission has been picked, and I'm not on it. Of course I've been feeling pretty low for the past few days. All of us are mad because Glenn was picked.

I was stationed at the flight test center at Wright-Patterson, and I was flying a wide range of airplanes and giving them a lot of different tests. It was a job that I thoroughly enjoyed.

This is what I wanted all along, and after I finished my studies and begun the job of testing jet aircraft, well, there wasn't a happier pilot in the air force.

Much of Indian science seems intuitive and not bound by the rigid thinking of classical scientists.

Science fiction has its own history, its own legacy of what's been done, what's been superseded, what's so much part of the furniture it's practically part of the fabric now, what's become no more than a joke... and so on. It's just plain foolish, as well as comically arrogant, to ignore all this, to fail to do the most basic research.

The progress of science is strewn, like an ancient desert trail, with the bleached skeleton of discarded theories which once seemed to possess eternal life.

Historically, science and society have gone separate ways, although society has provided the funds for science to grow, and in return, science has given society all the material things it enjoys.
