I want a plane.
The world has become a cynical and mean place. The guy bought a freaking working fire engine, and all people can do is whine endlessly about how impractical and wasteful it is...
But yet these same people wouldn't say the same about an aircraft, race car, or similar. Even though those are likely MORE expensive and equally as wasteful fuel wise.
Whatever, you get your plane! And you have fun with it. Ignore all these haters and cynics.
In reality, I like the idea more then the reality of it. If I really had a billion dollars I would simply buy a porsche and use all my free time to do research.
