Comments The second flight of the Hytest-1 rocket went without a hitch. the ascent was very straight, and on the second flight, the 2-stage recovery system had been dispensed in favour of a single stage deployment system. The difference in length seemed to provide added stability on the ascent, and coupled with a lower wind speed at the launch site, resulted in the straight trajectory.
