The Design and Construction of Epcot’s Spaceship*Earth
https://malloryobryant.wordpress.com/2011/09/13/the-design-and-construction-of-epcot%E2%80%99s-spaceship-earth/

Essentially, SE is two separate structures: the external shell which is the sphere itself and the internal ride system and show scenes.* From now on in this article, I’ll refer to them as either the Shell or the Show.*

The sphere-within-a-sphere design also addressed another issue: runoff of rainwater underneath SE.* By leaving one inch gaps between the Alucobond facets, rainwater trickles down to the waterproof inner skin where it accumulates at a hidden gutter system near the “equator” of the sphere and is then carried out to the World Showcase Lagoon.
