The engineering team at the Biggin HIll Heritage Hangar begin the rebuild of RAF Spitfire MJ772, a war veteran fighter that saw action in the skies over the D Day beaches and the battle to liberate Europe. The ambitious restoration begins with the left wing, torn off in a crash landing in a field in Kent after an engine failure. Chief engineer Franca Tambascia and his young team must replace the main spars and repair damaged metalwork twisted and buckled in the accident.
