A small plane on its way to Houston crashed shortly after takeoff from Addison Airport Monday morning, killing one of the three men on board. The plane went down in the 4200 block of Plano Parkway around 11:35 a.m. after reporting engine trouble and attempting to return to Addison Airport. The crash site is about 100 feet from Hebron High School. "We just heard the plane sputtering," said Ken Couch, who was nearby. "Then we heard a big ’swoosh,’ so we figured something was going on."
