The team get to work on the Spitfire's fuselage to get the 60-year-old parts back into shape, and there's a visit from a World War II veteran who may have a very special connection to the project.
The team get their newly-built fuselage off to the paint shop and restoration guru Steve gets to work rebuilding a long-forgotten cousin of the Spitfire - the Hawker Typhoon.
The team take on the biggest challenge of the restoration - attaching the wings - and veteran Hawker Hurricane pilot Archie McInnes tells his astonishing story of survival.
With their warbirds due to star in the Biggin Hill air show, the team get to the paint shop for some crucial components. And a Women's Auxiliary Air Force veteran recalls her experiences from the war.
Peter puts the newly restored Merlin through its paces. Pilot Jez explores the little-known history of the Spitfire as a reconnaissance aircraft. Ground crew chief Ray meets a Fleet Air Arm veteran.
After two years of hard work, the Spitfire is nearly complete and the team prepare for the maiden flight, but will she fly? And factory owner Peter gets ready for his next project.
