Not something the Swedish Air Force can do either - it's a private organisation
Four aviation enthusiasts started the business in 1997 and since then the number of aircraft and members has steadily increased in number. The business is managed by a board authorized by the Swedish Transport Agency and the work is carried out on a voluntary basis by certified pilots and technicians, most of them with an air force background. The aim is for the aircraft, which are civilly registered, to be painted and equipped as at the time they flew in the Air Force.
