how do they get the balloon back?
As soon as it was confirmed that Baumgartner had landed safely, the attention of mission control shifted to the balloon and capsule. The team remotely detached the capsule from the balloon, allowing it to fall back to Earth under its own parachute. It hit the ground 55 miles east of Baumgartner's own landing site. The balloon was deflated via a nylon "destruct line", with the lightweight balloon material – known as the envelope – falling back to Earth to be gathered and removed by truck. The capsule could, in theory, be used again, but the balloon envelope can only be used once.
