I think I understand.
My father took me for my first airplane trip when I was ten. I sat by the window and used a whole roll of film taking stupid pictures of the wing. Later in life, I would always try to sit by the window, unless there happened to be a child nearby who wanted to trade seats.
There's something thrilling about the takeoff run, the takeoff itself, the steep banks when turning, the turbulence, and the landing. Hell, there's something thrilling about calmly drinking ginger ale or using the lavatory while moving 500 miles per hour at 30,000 feet. Even on a long, boring flight, when nothing's going on, meditating on the planet slowly going by beneath you gives you a new perspective on everything.
I don't think I would ever pay $2000 just to fly around, but the idea isn't completely alien.
