$75,000 balloon ride to lift passengers 30 km into space

The video tutorial describes a helium balloon guided by a parachute, capable of carrying six passengers and two pilots in a pressurized capsule. The balloon ascends for 90 minutes to reach the stratosphere, where it remains for two hours before descending. At 30 kilometers, it reaches over twice the altitude of conventional airplanes but is still far from outer space. The initial launch is planned at Spaceport America in New Mexico.
