The USAF Thunderbirds perform a Diamond loop in their F-16C 'Falcon'. The Diamond is flown by Lt. Colonel Kevin Robbins (#1 Commander/Leader), Major Scottie Zamzow (#2 Left Wing), Major Nicole Malachowski (#3 Right Wing), and Major Steve Horton (#4 Slot).

Diamond: Historically, as Thunderbirds 1 through 4 lift off, the slot aircraft slips immediately into position behind 1 to create the signature Diamond formation. Thanks to the 2009 upgrade to the Block 52, the Diamond now has more than enough thrust to continue to climb straight up into their first maneuver, the Diamond Loop. -[wiki]
