Looks kind of cool, but I think they should just relaunch dirigibles. It's been pretty well proven that the Hindenburg disaster resulted not from its hydrogen, but from the hyper-flammability of its skin. So there's really no reason to worry about them exploding, so long as modern materials are used to skin the things. I'd love to travel by dirigible. I've always wished we still had that Golden Age view of getting there being half the fun.

Very cool but instead of being Diamond Shaped they should be round, like a ball........or a Death Star:)

I was going to book a passage, but you've put me off now. ;)
