The Blue Angels' show season runs each year from March until November. They perform at both military and civilian airfields, and often perform directly over major cities such as San Francisco's "Fleet Week" maritime festival, Cleveland's annual Labor Day Air Show, the Chicago Air and Water Show, Jacksonville's Sea and Sky Spectacular, Milwaukee Air and Water Show, and Seattle's annual Seafair festival.

During their aerobatic demonstration, the Blues fly six F/A-18 Hornet aircraft, split into the Diamond Formation (Blue Angels 1 through 4) and the Lead and Opposing Solos (Blue Angels 5 and 6). Most of the show alternates between maneuvers performed by the Diamond Formation and those performed by the Solos. The Diamond, in tight formation and usually at lower speeds (400 mph), performs maneuvers such as formation loops, rolls, and transitions from one formation to another. The Solos showcase the high performance capabilities of their individual aircraft through the execution of high-speed passes, slow passes, fast rolls, slow rolls, and very tight turns. The highest speed flown during an air show is 700 mph (just under Mach 1) and the lowest speed is 120 mph.^[2] Some of the maneuvers include both solo aircraft performing at once, such as opposing passes (toward each other in what appears to be a collision course) and mirror formations (back-to-back. belly-to-belly, or wingtip-to-wingtip, with one jet flying inverted). The Solos join the Diamond Formation near the end of the show for a number of maneuvers in the Delta Formation.
The parameters of each show must be tailored in accordance with local weather conditions at showtime: in clear weather the high show is performed; in overcast conditions a low show is performed, and in limited visibility (weather permitting) the flat show is presented. The high show requires at least an 8,000-foot (2,400 m) ceiling and visibility of at least 3 nautical miles (6 km) from the show's centerpoint. The minimum ceilings allowed for low and flat shows are 3,500 feet (~1 km) and 1,500 feet (460 m), respectively.^[6]

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.^[7] 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.^{[citation needed]}
The official Blue Angels insignia was designed by then team leader Lt. Cmdr. R. E. "Dusty" Rhodes and Virginia Porter (Illustrator for Naval Air Advanced Training Command), then approved by Chief of Naval Operations in 1949. It is nearly identical to the current design. In the cloud in the upper right quadrant, the aircraft were originally shown heading down and to the right. Over the years, the plane silhouettes have changed along with the squadron's aircraft. Additionally, the lower left quadrant, which contains the Chief of Naval Air Training insignia, has occasionally contained only Naval Aviator wings.^{[citation needed]}
Originally, demonstration aircraft were navy blue (nearly black) with gold lettering. The current shades of blue and yellow were adopted when the team transitioned to the Bearcat in 1946. For a single year, in 1949, the team performed in an all-yellow scheme with blue markings.^[8]

Current aircraft

The Blues' McDonnell Douglas F/A-18 Hornets are former fleet aircraft that are nearly combat-ready. Modifications to each aircraft include removal of the aircraft gun and replacement with the tank that contains smoke-oil used in demonstrations, and outfitting with the control stick spring system for more precise aircraft control input. The standard demonstration configuration has a spring tensioned with 40 pounds (18 kg) of force installed on the control stick as to allow the pilot minimal room for uncommanded movement. The Blues do not wear G-suits, because the air bladders inside them would repeatedly deflate and inflate, interfering with the control stick between the pilot's legs. Instead, Blue Angel pilots tense their muscles to prevent blood from rushing from their heads and rendering them unconscious.^[9]
In July 2016, Boeing was awarded a $12 million contract to begin converting the Boeing F/A-18 E/F Super Hornet for Blue Angels use, to be completed by September 2017.^[10]

The show's narrator flies Blue Angel 7, a two-seat F/A-18D Hornet, to show sites. The Blues use this jet for backup, and to give demonstration rides to VIP civilians. Three backseats at each show are available; one of them goes to members of the press, the other two to "Key Influencers".^[11] The No. 4 slot pilot often flies the No. 7 aircraft in Friday's "practice" shows.
The Blue Angels use a United States Marine Corps Lockheed C-130T Hercules, nicknamed "Fat Albert", for their logistics, carrying spare parts, equipment, and to carry support personnel between shows. Beginning in 1975, "Bert" was used for Jet Assisted Take Off (JATO) and short aerial demonstrations just prior to the main event at selected venues, but the JATO demonstration ended in 2009 due to dwindling supplies of rockets.^[12] "Fat Albert Airlines" flies with an all-Marine crew of three officers and five enlisted personnel.
