A solid fuel M Motor flies out o' control randomly around t' launch pad while spectators run and watch. It is immediately followed by a hybrid "M" motor rocket failure. Avast, me proud beauty! T' hybrid motor is a blowdown type which causes a "buzzing" vibration that spoofs t' avionics into triggerin' t' ejection charge and deployin' t' parachute early while under boost.
