Bob Geldof, because he changed the perception of what people should do when they see a situation of need.

Sir David Attenborough, John Prendergast.

Martin Sheen, simply the kindest and most fun-loving person and serious activist I’ve ever known. If Jesus was alive today he’d point to Martin Sheen and say, “That’s what I was talking about.”

Bill Drummond, Thomas Bangalter and Jay-Z.

I didn’t like it at all. This problem is called Meniere’s syndrome. It causes dizziness, nausea, lack of balance and so on. The prediction was that in some cases it was correctable. I said, “In my case it is going to be correctable.”

No, I didn’t. Certainly when I was in the one-room country school you described, I guess my ambition at that point was to get through with a creditable performance. Really, of course, nobody thought about astronauts in those days, but I didn’t really even start thinking about airplanes very much when I was in grade school. So that interest sort of came later on.

A little bit of overconfidence perhaps. A lack of attention to duty. Little insidious things that happened. You had this great team of dedicated, qualified people, but they get a little bit complacent, and boom! Pretty soon something goes wrong.

And I say, “Every single dollar that was spent on the space program, went into the pockets of the individuals who worked on it: the contractors, the subcontractors, the vendors. It went to feed their children, put clothes on their back, send them to school.…If we are going to be the leaders of the world, and we are going to worry about trade balance, if we are going to worry about military systems, or solving the problems of the environment, we are going to have to continue to spend money on research, medical research as well.

And I think that still is true of this business — which is basically research and development — that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

Pretty good, I think. I didn’t mind studying. Obviously math and the physical science subjects interested me more than some of the more artistic subjects, but I think I was a pretty good student. Obviously the teacher thought so.
