Build and flight video of Super Sonic I for my NAR HPR L3 certification. Super Sonic I is the first iteration of two stage high altitude rockets. This build was the sustainer for Super Sonic I. Super Sonic I was flown on a CTI M-1830 to 12,836 feet at a top speed of Mach 1.28. The launch took place at ROCStock 50, in Lucerne Valley, CA. I was accompanied by my university's rocket lab, Embry-Riddle Prescott's Rocket Development Lab. The booster was not built since it has been redesigned to be work with Super Sonic II.
