I have always wondered why the high performance "personal jet" concept isn't more popular. I mean you can only get so much out of sports cars...
The number of people who have the financial means to purchase, say, a $200,000 Lamborghini, a $400,000+ Ford GT, or even a $1,500,000 Bugatti is much larger than the number who can purchase, maintain, insure, and operate a $65,000,000 Gulfstream G650.
And it's easier to get a driver's license than a jet pilot's license.
