The project started with the full removal of the front glazing system, followed by the careful extraction of all suspended and static aircraft. Two coats of UV-resistant resin paint were applied to the exhibition flooring before aircraft were returned. During the glazing removal, 18 damaged panels were discovered, adding over £100k in unforeseen costs. In total, more than 1,200m² of 19mm thick toughened glass was removed over six weeks.
While off display, vital conservation and restoration were carried out on the aircraft. Once completed, the aircraft were reinstalled in a newly reconfigured layout. The glazing system was then reinstated with new frames, seals, gaskets, and an ultraviolet film to protect exhibits from sun damage. A final third coat of floor paint was added, and new power and data outlets were installed throughout the hangar in preparation for interactive consoles, later fitted by a specialist contractor.
