Just like when early airplanes were flying in 1910, we didn't know what the benefits are, but we were doing it because it was fun.

The criticism is, once I get something flying, I lose interest in it.

I spent about seven years during the Vietnam War flight-testing airplanes for the Air Force. And then I went in and I had a lot of fun building airplanes that people could build in their garages. And some 3,000 of those are flying. Of course, one of them is around-the-world Voyager.

By 1931, after a few years' experience of flying scheduled airlines, those planes were operating at roughly 600 times the safety of the space shuttle. I look at safety not in terms of fatalities per passenger-mile, but when you get in and close the door, what is the risk of dying on this flight?

They did the whole Derrick Thomas tribute and had the airplanes flying over the stadium,

That's the thing about flying: You could talk to someone for hours and never even know his name, share your deepest secrets and then never see them again.
