For those of you who have been lucky enough to fly on a private or charter jet (I have not yet), I have a question.

On most airlines, it seems flights more than an hour, almost everyone ends up closing their window shades, turning the plane into a dark room. What is it link on business jets - is it the same? On one hand I imagine the people who fly these fly often enough they don't bother looking out, on the other hand the interiors are a lot better and maybe not so much an incentive to close them.
