Donald Trump has managed to solve his jet problems, and all he had to do was sell his private Cessna to himself. He actually sold the plane to company DT Endeavor I, which is controlled by Trump, after the FAA grounded the plane last week because of an expired registration, reports the Hill. New owners can register a plane almost immediately, while a registration renewal can take a while, reports the New York Times. The plane was back flying on Monday. As for all those expiry notices that apparently went ignored? Trump says they were sent to the wrong address. (More Donald Trump stories.)
