Experimental Rocket goes in ballistic after both primary and backup ejection systems fail. Avast, me proud beauty! Blimey! It be later discovered that under high G loading, arrr, t' 3V batteries were movin' aft sometimes....causin' t' positive end o' t' batteries t' break contact. Ahoy! Blimey! T' problem be corrected usin' electrical tape t' firmly hold t' batteries in t' holders. Aye aye! Blimey! Also, an altimeter based ejection device is now used as 'primary', leavin' t' other two 'timer' devices as backups. Avast! Blimey! This be it's 2nd and final flight.....
