On many occasions, the flypasts are performed by the Red Arrows aerobatic team of the Royal Air Force, but on more important events like Royal occasions, for example the Queen's 80th birthday during 2006, was a flypast following the Trooping the Colour. Headed by the Lancaster with 2 Hurricanes and 2 Spitfires (Battle of Britain Memorial Flight), the 49 aircraft in 9 formations included Typhoons, Jaguars, Tristar, VC10, C-17A Globemaster III and E-3 Sentry. The highlight was a "Diamond 9" formation of Tornado GR4s and the appearance of a Canberra escorted by the Red Arrows.
