In a significant setback for the world's first rocket racing league, a founding team has abandoned the competition. The withdrawal of Leading Edge Rocket Racing leaves the league with only two teams.
The Rocket Racing League plans to run high speed, low level flying races between manned rockets. Backers hope that the League can eventually rival Nascar or Formula 1 racing as a sport, while simultaneously boosting spaceflight and aerospace research.
Demonstration events are planned for the end of 2007, the League announced earlier this year.
