4 Corners Rocketry Association September flights. First rocket be a Markarian 231 on an Aerotech 1500 Mojave Green that successfully flew t' 16000' and landed close t' t' launch site. Arrr! T' second was a custom 2" rocket on an Aerotech H195 Blue Thunder that lost 2 fins durin' t' flight. Begad! (My first high power shred!) Simulation predicted 30+ Gs and Mach 0.8 after 1 second o' flight.
