In a separate building, No. 141 Boston Sqdn and 2266 (Spilsby) Sqdn of the ATC have created a display showing the past and present activities of the Corps' 31 Squadrons in Lincolnshire. The Corps was founded in 1941 to provide young people with Royal Air Force background training and experience. Exhibits include a home made flight trainer (shown below, right) and extensive photograph and document displays.
