Balloon flightIn 1998, Andy Nelson and navigator Bertrand Piccard, in the Breitling Orbiter II set the world record for endurance at nine days and 17 hours - or, to be exact, 233 hours and 55 minutes. But the journey was stopped when they were not allowed to over-fly China. The preparation took more than four years with a team of 13 people. Bertrand is the grandson of the balloon flight pioneer, Auguste Piccard. With Brian Jones, Bertrand accomplished the first complete non-stop round-the-world flight on 21 Mar 1999 in the Breitling Orbiter 3. |
