(Project numbering): To keep track of the history, each project has been given a number. This number is attached to the assigned commander of the planned flight. Changes in crew, sponsor or balloon does not affect this number. When Per Lindstrand/Richard Branson joined with Steve Fossett and changed main sponsor, the new project was however given a new number. The projects are listed in order of first appearance. Sorry for sequence of projects 09 to 12. Mistake but a change will affect other lists.
When a project has progressed to a point when an actual launch has been possible or has actually resulted in a flight, this has been counted as an attempt.
All attempts that have resulted in a take off.
