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