Congratulations to George and the team from Air Command Rockets on their recent water rocket world record.
The Horizon project has been under construction for more than 6 years and is almost certainly the most sophisticated water rocket ever built.
In August Horizon flew for the first time and the launch went exactly to plan. The second stage flew over 1 mile high or 1.62km. A remarkable achievement for a rocket powered by nothing more than water and compressed air.

While there is no official worldwide body that sanctions water rocket records we believe this flight is approximately double the altitude that any other team has achieved.
A video showing highlights from the flight can be seen here:
