Boeing just took $20 billion and 10 years to improve the efficiency of their planes by 10 percent. That's pretty lame. I have a design in mind for a vertical liftoff supersonic jet that would be a really big improvement.

I think there are too many smart people pursuing internet stuff, finance, and law. That is part of the reason why we haven't seen as much innovation.

If others would think as hard as I did, then they would get similar results.

Ability to think, like the violin or piano, requires daily practice.

I don't spend my time pontificating about high-concept things; I spend my time solving engineering and manufacturing problems.
