This is me Estes Super Neon XL boostin' on an Aerotech E20-7 single use motor. Begad! T' "up" part went great but t' parachute failed t' deploy so t' "down" part be sub-optimal resultin' in a detectable seismic event. T' good news is that t' nose cone and fin can are in good shape so I can rebuild it. We have t' technology... Arrr! Rocket Science: Makin' everythin' else look simple since 1958!
