This is a flying semi-scale model of the Viking sounding rocket, which was developed by the US to provide a better vehicle than the German V2. In the 1950's, several of the Viking rockets were designed and flown by the US Navy. As part of a scientific mission, the Viking 7 climbed to 136 miles, and beat the altitude record of the V2. This rocket flies to more reasonable altitudes on a cluster of 2 model rocket motors. Try two B's for a smaller launch site, or go wild with two C motors.
