Microsoft co-founder Paul Allen has spent the last six years working on a giant aircraft capable of launching rockets to space. It's not quite ready to fly, though. Over the next few days, each of the six fuel tanks will be filled independently to make sure that the tanks are properly sealed and that the fueling mechanisms work. How big is it? On a football field, the wingtips would extend beyond the goalposts by more than 12 feet on each side. Video of the rollout here.
