6 years ago, I was on the book-tour circuit discussing my book Free Flight, which had just come out. It was about several parallel innovations in the aviation biz — more efficient engines, cheaper and better ways of building planes, safer ways to navigate and control the planes — that might together make “air taxis” part of the solution to the misery of hub-and-spoke airline travel.

air taxis are here.

The only crowded parts of today’s system—the runways and approach paths to the big hub airports—are precisely the places air taxis plan never to go. The DayJet planes fly at altitudes basically unused by other aircraft, 4500-7500m. (Very small planes fly lower than that; airliners and corporate jets fly higher.) “What’s the biggest airport we’ll ever go into?. A place like Savannah or Knoxville. Where the airlines are is where we don’t want to be.”
