 In 2005, the U.S. Air Force Thunderbirds ended their demonstration halfway through their routine.During a diamond formation slow-roll pass, the tip of the missile rail on the right wing of the slot (#4) aircraft contacted the left stabilator of the right (#3) aircraft.A four-foot section of the missile rail snapped off, while the #3 aircraft sustained damage described by one of the Thunderbirds pilots as a "medium deep scratch" to the red paint of the stabilator.
