Scott Hertel and Guy Hardy flew their 17 foot 350 pound rocket named “8URKT” on an EX Q motor (115k nS) to 77,484′ AGL (81,383′ MSL) with GPS-1 onboard to claim the TRA altitude record for the single stage Q EX motor class!  GPS-1 recorded the full flight profile from take-off to landing; the most interesting portion of the flight data shows the vehicle exceeded Mach at 1,654 AGL (5,553 MSL) and decelerated back to Mach at 63,568′ AGL (67,467 MSL); it then coasted on for another 10,017 feet to an Apogee of 77,484′ AGL (81,383 MSL) or 14.67 statute miles!
