On 11 July 2008 Royal Air Force aircraft flew in formation over RAF Fairford as HM Queen Elizabeth II presented new Colours to the Royal Air Force and the RAF Regiment as part of the 90th anniversary celebrations of formation of the RAF in 1918. The aircraft formations, together, involve a total of 90 aircraft, one for every year of the RAF’s existence to date. The total length of the formations was 35 miles.
The only formation bigger than this was the flypast marking the 50th Anniversary of the Battle of Britain, in 1990, when 168 aircraft flew over Buckingham Palace.
