Tropical Island

I've basically been trying to sleep all day today, so I'm turning to Fact of the Day to nip this learning thing in the bud before the sun goes down:

The largest building in the world by volume is the main assembly building at the Boeing manufacturing site in Everett, Washington, USA.

The hangar houses 472 million cubic feet of space - well, they do build planes in it. I got onto this rather uninspiring topic because the Fact of the Day website told me that the largest building in Earth without interior supports is the Goodyear 'airdock' (like a shed for an airship, basically) in Akron, Ohio. The same site (now starting to lose credibility) claimed that it's so large, clouds form in the top and it rains indoors. Really? According to Wikipedia, no - it's condensation in the roof which leads to a wet mist falling down to ground level. Kinda sounds like rain to me.

I then, however, discovered that a German airship company called CargoLifter (stay with me here) constructed a larger building in East Berlin in 1999. This doesn't make a lot of sense, as airships have got a lot smaller since the Goodyear hangar was built. With cost-effective planning like that, it's little surprise that the company went bankrupt, and their enormous skydome, or whatever, now houses a rather cheap-looking swimming pool/restaurant combo affair. I don't know if the Boeing site does have internal supports, or a tropical theme, and frankly, I don't really care. So let's just leave it at that - sometimes, like life, learning is boring, unsatisfactory and thankless. Bah!
