Short answers, pulled from the story.
Construction crews drove the first steel foundation pile into the Florida bedrock on the 2nd of August 1963. This action marked the official start of building what would become the Vehicle Assembly Building.
The Vehicle Assembly Building was designed to stack Saturn V rockets vertically onto mobile launch platforms for the Apollo program. It currently supports modern missions while retaining its original vertical assembly capabilities for the Space Launch System rocket.
Four high bays dominate the north end of the facility with enclosed spaces for stacking rocket stages. Each bay features doors standing tall enough to swallow entire shuttle orbiters whole that comprise seven vertical panels and four horizontal sections taking forty-five minutes to open or close.
Hurricane Frances blew off 850 aluminum panels from the exterior walls creating new openings covering hundreds of feet across the building sides. Storm season of 2004 brought this destruction which left damage visible throughout 2007 despite repairs beginning in early 2007.
Workers painted an American flag onto the building as part of United States Bicentennial celebrations in 1976. Workers began restoration efforts in early 2007 to fix damage from decades of storms after the flag had been previously repainted in 1998 for NASA's fortieth anniversary celebrations.
