Don't get too excited, it's not ready for tourist crossings of the Atlantic. Instead, the Bullet 580 will be carrying NASA research payloads. At least at first. Made with a Kevlar balloon filled with helium, the world's biggest airship is maneuverable and can be controlled by a pilot, as well as by remote control. There doesn't seem to be any physical reason why it couldn't carry passengers.
All the action in this 2-minute video took 6 hours in real life. Sped up, it looks like a gaggle of humans caring for some monster grub.
