The Assault Glider Trust Airspeed Horsa has been built from scratch using original plans and by examining surviving aircraft components. Although the plans show a great deal of detail, they are mostly ‘assembly’ drawings and are often lacking measurements and sizes. This has required the volunteer workforce to do a lot of ‘reverse engineering’ in order to make everything fit together correctly. The aircraft has been built using original techniques and original parts have been incorporated wherever possible. Although the Horsa is being built to flight condition, it will not be flown.
