Delta Pass In Review 2

Thunderbirds Delta BUP (bottom-up pass), more commonly called the Delta Pass in Review. The Delta and the series of maneuvers associated with it, have special meaning to all Thunderbirds past and present. They represent that special pride, perfection, and commitment to excellence that makes the United States Air Force, and those who serve in it, the very best in the world. Sun 'N Fun 2008.
