Set on an active airfield, the museum houses iconic machines such as the Hawker Hunter, D.H. Vampire, along with the only T2 BAe Harrier remaining worldwide. Unusually, visitors may enter the cockpits of some of the aircraft and find out what it is like to sit in the narrow confines of a jet fighter aircraft. Part of the museum is devoted to the creation of the RAF Mountain Rescue Service, started here at RAF Llandwrog in 1942, whilst other sections describe the wartime airfields of North Wales. The gift shop sells model kits, remote control helicopters, quadcopters (drones), rockets and souvenirs.
