...with the other building to form an enclosed, weather-protected space where the rest of the shuttle vehicle can be assembled. Like the tower, the assembly building will have a crane in its roof. Together the two machines can hoist the empty, 154.4-ft.-long, 69,000-lb. external tank of a future shuttle into place between the stacks of rocket boosters. Clearance on each side: less than ¼ in. The final element in the assembly, the main body of the shuttle, or orbiter, is mounted on the external tank by means of a double crane...

The system called for a tolerance limit of as much as ¼ in. in fitting the orbiter to the tank. NASA said no, setting the maximum permissible degree of variation at a minuscule ³¹/iooo³¹∕¹ººº in. "With the wind and the weather at Slick Six, we knew we could never get it down to that," says Major Ronald L. Peck, Vandenberg...
