USAF Thunderbirds #1-4 perform the Diamond 360 into an Arrowhead Loop. <= The four F-16 'Falcons' are flown by Lt. Colonel John Caldwell (#1 Commander/Leader), Major Will Graeff (#2 Left Wing), Captain Michael Brewer (#3 Right Wing), and Major Whit Collins (#4 Slot).

Much of the Thunderbirds' display alternates between maneuvers performed by the diamond, and those performed by the solos. They have a total of 8 different formations: The Diamond, Delta, Stinger, Arrowhead, Line-Abreast, Trail, Echelon and the Five Card. The Arrowhead involves maneuvers in tight formation with as little as 18 inches fuselage to canopy separation. The #4 slot pilot flies as close as 18 inches to the commander, #1, during the arrowhead loop. All maneuvers are performed at speeds of 450 to 500 mph.-[wiki]
