A pilot from Virginia removed his son’s loose tooth using a helicopter. Rick Rahim, from Virginia, flies helicopters for a living, and when his seven-year-old son’s tooth became loose, he did not waste time by tying it to a door handle. Instead, Mr. Rahim tied one end of a string around his son’s tooth and the other end to his full-sized commercial helicopter. The father of four posted a video clip of his playful venture on Facebook, advising parents to do fun and creative stuff with their kids. The video shows him launching the helicopter into the air and flying just far enough to successfully remove the loose tooth. At the end of the video, Mr. Rahim assures watchers that the circumstances were safe, and that he has 13 years of helicopter flying experience behind him. "You’ve got to do everything safe in life, and that’s what I did today," he said. Mr. Rahim later said that although some parents have used remote control helicopters to pull teeth before, he might be the first to use a full-sized aircraft, as he can’t find evidence that it has been done before.
