This crazy Airborne Metro, if ever built, could reduce emissions from air travel 80% by revolutionizing the way we fly. The giant, 3,000 passenger craft is a nuclear powered airport and shuttle in the sky that allows smaller aircraft to bypass making long distance flights by landing on its back and dropping passengers off. In the future, the designers of this massive hunk of steel envision passengers taking regular jets from the ground to Airborne Metro, and then having the Airborne Metro make the long haul to a far off population hub where passengers hop onto regular jets that shuttle them to their final destinations.
