Explaining The Universe on Instagram: "The Boeing Everett Factory in Washington State is so large that it has occasionally formed clouds inside the building. Covering over 98 acres of floor space and enclosing 472 million cubic feet of volume, it’s the largest building in the world by volume. The factory is where Boeing assembles massive aircraft like the 747, 767, 777, and 787 Dreamliner. • #explore #reels #viral #universe #explaining #space"
