The Air Force has disciplined four pilots for buzzing the practice field of the NFL Carolina Panthers. The Guardian newspaper reported that the four, based at Moody Air Force Base, Ga., were placed on restricted duty after reports emerged that they flew their A-10C Thunderbolt IIs at low altitude over Bank of America Stadium in Charlotte, N.C., while the Panthers were practicing. Panthers coach Ron Rivera told the Guardian that the planes passed low enough for the players to see the pilots waving at them.
