Where is the main RAF show held every year?

The main RAF show, known for showcasing the capabilities of the Royal Air Force and attracting large audiences, is held at RAF Fairford. This location is particularly significant due to its spacious airfield and facilities that can accommodate a wide array of aircraft and displays, making it ideal for hosting large-scale events. RAF Fairford is also traditionally associated with the Royal International Air Tattoo (RIAT), one of the largest airshows in the world, typically featuring a variety of military and civilian aircraft from different nations, flying displays, and static exhibits. This prominence in aerial displays and the cultural significance of being a focal point for the RAF's public engagement efforts makes RAF Fairford the correct answer.
