From a Jack Shafer column on politico.com headlined “The Rupert Murdoch Retirement Myth”:

Rupert Murdoch’s preferred mode of transportation has always been the shock wave. Where other media moguls might carefully plot with a compass and protractor a safe and steady path through the minefields of life and commerce, Murdoch has always relied on the high torque of a jet. Moving with the stealth of a predator, giving no advance notice on his destination, by the time he blows by, roar and rumble are the sole artifacts of his supersonic passing.
