The climate-controlled, pressurized interior cabin will be held aloft by a balloon as it rises to the stratosphere. Reaching a height of 20 miles (30 kilometers), passengers will have a 360-degree view of their surroundings, from which they’ll be able to see the curvature of Earth. The passengers will be able to see 450 miles (724 km) in any direction, as well as the blackness of space. By comparison, passenger jets fly at heights reaching 7.9 miles (12.7 km).
