High Power Rocketry
The first High Power Rocketry hybrid flight was at the 1996 International Rocket Weekend at Largs in Scotland, when Scott Bartel of Black Sky Research launched a Black Sky Research Optimal rocket on a Hypertek J-class hybrid rocket motor, in August 1996. This was followed up the next year when he launched the same rocket on a Hypertek J-class hybrid rocket motor at the UKRA '97 launch event in July 1997. The first flight of the R.A.T.T. Works High Power Rocketry hybrids in the U.K. took place in 1999.
Amateur Rocketry
The first known flight of an amateur hybrid rocket in the U.K. (as opposed to High Power Rocketry), was by the MARS (MARS Advanced Rocketry Society) in September 1998. The first known static test firing of an amateur hybrid rocket motor was by the Orbital Rocketry Society in 1993.
