This makes me kinda sad. If I had to choose between having a weird and awesome indoor water park like that, Or having airships be popular... I'd rather have airships.,(reply>), @ain You're just as wrong, especially about the fire part. I get it, you saw the Hindenburg once, and now you're an expert. But you're not, at all. Why is this still a misconception? They use helium, and the most recent ones have composite materials, not cloth. The only fire that could happen is an engine fire, and that's not the end of the world. The Hindenburg had hydrogen cells and a flammable envelope. Not the same as the Goodyear Blimp or the Airlander which is a hybrid airship, can carry heavy equipment while being very very efficient.,(reply>), @rashakor  Bruh, I want a zeppelin RV / Mobile home.,(reply>), EnderSquid 11 Zeppelins were faster than most ground vehicles, could carry loads vastly larger than any planes. The only competition were really the helicopters at similar payloads. Cargolifter prototypes, which were the ships supposed to be built in this hangar, were aiming for the niche between Helicopters and planes, beating both in safety and energy efficiency by orders of magnitude. They were also supposed to be able to deliver payloads directly to destination (think wind turbines) As it turn out though, that niche is a little narrower than anticipated. Actually another company Zeppelin NT is still in business.,(reply>), @EnderSquid 11 they're fuel and power efficient. with newer lighter materials like aerogel, they become even more efficient.,(reply>), They're slow, really space inefficient, really expensive, but they look rad as hell so I totally agree
