Why don the Blue Angels and the Thunderbirds fly together?
Current Department of Defense policy is to maximize use of military aviation demonstration teams for recruiting and to demonstrate U.S. military aviation abilities to the public. This is best accomplished by having the Air Force and Navy flight demonstration teams perform separately in as many locations as possible throughout the year. However, the Thunderbirds do perform at air shows with the U.S. Army parachute demonstration team, the Golden Knights, as do the Blue Angels.
