The maximum ceilings allowed for low and flat shows are 3,500 feet (~1 km) and 1,500 feet (460 m), respectively.
Origin of squadron name, insignia and paint scheme
When initially formed, the unit was called the Navy Flight Exhibition Team. The squadron was officially redesignated as the United States Navy Flight Demonstration Squadron in December 1974. The original team was christened the Blue Angels in 1946, when one of the pilots came across the name of New York City's Blue Angel Nightclub in The New Yorker magazine; the team introduced themselves as the "Blue Angels" to the public for the first time on 21 July 1946, in Omaha, Nebraska.
