Sometimes, one plane just isn't enough, you know?
It looks like Elon Musk recently took ownership of a 2008 Gulfstream G550, for what we're hearing is about $14.3 million. It's registered to Falcon Landing LLC, which has the same address as SpaceX's headquarters, but it seems to be for Musk himself. (Though Tesla reportedly foots the bill for most of his travels.)
He's been shopping for at least two years, and evidently finally found his plane. I'm guessing it wasn't the Matterhorn White exterior or the Rolls-Royce engines, but the built-in printer that sold him. (Check out the full listing to take a look inside.)
For a guy who flies as much as 150,000 miles a year, maybe one plane really doesn't suffice. That, or little X Æ A-12 is about ready to start hitting the skies.
