Carbon Edge 54/38 Altitude Flight
Black Rock Desert, September 13, 1998


My Carbon Edge 54/38 rocket reached an altitude of 23,689 feet flying on a K250 staged to an I132, with redundant electronics for upper ignition, booster ejection, and upper ejection. Both motors were "plugged" (they had no built-in parachute ejection charge). Adept altitude data is shown here, mathematically smoothed with median and 4-th difference filters, along with altitude-derived velocity.
