David Geffen, P. Diddy, Rolling Stones (?) - but I don't think any of these own a 747. However, just because musicians don't own one doesn't mean the can't own one. I would argue in the corporate world they are likely treated as corporate, rather than private, expenses. In the acting industry, many own private jets (or, in Travolta's case, five).

The easy path is through the mainstream - if you're willing to give in to The Man (tm).
