If I were a stockholder in a company that bought one of those planes...
I'd scream bloody murder about waste of corporate funds. As it is, A Gulfstream IV costs somewhere around $30 million. If that plane is ever built, it'll probably cost upwards of $100 million. I have a hard time seeing how the plane could be economically justifyable. Of course, I _might_ be a little more understanding if they let me get some stick time....
