A 7-year-old border collie named Piper has won the hearts of hundreds of Internet users after a photo of him working at the Cherry Capital Airport in Traverse City was posted on a popular online social forum. Airport operations supervisor Brian Edwards, who’s also the working dog’s owner, told the Traverse City Record-Eagle that he was surprised to come into work at 4 a.m. this week and discover that the airport’s website was experiencing network problems.
