The doors on the 39-year-0ld Vehicle Assembly Building are getting a needed face-lift to repair the damage caused by prolonged exposure to the Florida environment - one of the most corrosive in the nation. The North Transfer Aisle and the High Bay 3 Vertical and Horizontal doors have entered a 13-month restoration period. Extensive corrosion damage exists on the interior of the framework of the existing doors in both locations. All exterior siding is to be replaced, as well as all the hardware. The work contributes to the ongoing safety and infrastructure upgrade efforts at Kennedy Space Center.
