Re: “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 respect what the guy has done. But a vertical liftoff supersonic jet is going to be more difficult than anything he had encountered, including rockets.
His entire life seems to have been spent doing progressively harder things. I would be surprised if he decided what he is currently doing is as hard as it is going to get.
