The Boeing Factory in Everett, north of Seattle, the largest factory by volume in the world is so massive that it started to develop its own weather system forcing them to design a custom air conditioning system.
A state-of-the-art air circulation system had to be installed inside the monolithic manufacturing plant because clouds - the product of accumulated warm air and moisture - were forming inside.
I don't really know why I found that interesting enough to share. Thanks for your patience.
I lived in Seattle in the 1980s when Microsoft was just a start up that nobody had heard of and Boeing was the only game in town. Their massive factories were interesting to look at for just that reason. The scale of their facilities compared to everything else around was a bit surreal.
I got a feel for the scale of the 747s when I used to commute between Kuala Lumpur and Singapore. When you got on in Singapore it was from an air bridge. In Kuala Lumpur in the old airport, you would walk out to the plane and climb on by stairs. Massive, very glamorous and indadvertent cloud makers.
