The 511th Fighter Group arrives at Archbury to escort the 918th on the home leg of a shuttle mission. On the way Lt. Col Troper attacks a train making him 10 minutes late for the rendezvous. The 511th does not give the proper recognition codes and one pilot is shot down. Back on the ground Colonel Gallagher orders a brief at 0400, but only 12 of the fighter pilots show up. Gallagher has Troper put under house arrest.
