This week, the Federal Aviation Administration grounded Donald Trump’s Cessna Citation X business jet, which flew as recently as Monday despite being unregistered since January 31.

According to records maintained by the Federal Aviation Administration, one of Donald Trump’s airplanes—his 1997 Cessna 750 Citation X jet, which flew as recently as Monday—is not actually registered to fly. The lapsed registration was first reported by the New York Times.

You know who hasn't been so happy to see so many corporations shed their fancy private jets in recent months? The companies that manufacture them, not surprisingly. Cessna is now planning to run an ad campaign to counter the perception that flying private is a big waste of cash. Says the head of one industry trade group: "The vast majority of the time, these jets are flying offices, where people can conduct business and have confidential discussions that could never occur on a commercial jetliner." Isn't that what airplane lavatories are for? [WSJ]

Courage; Good Judgment; The confidence to forge ahead. These are just a few of the attributes that businessmen who own private jets possess. Frugal businessmen who've given up their jets, however, are bitch-ass punks.
