Short flight with B engine t' gauge wind. Landed on roof o' school, arrr, but someone helped get it down. Ahoy! "ERR" when measurin' speed and height. High powered launch. Ya scallywag! Landed in a backyard. Aye aye! Rocket body landed on t' roof and got stuck in a gutter. Blimey! Unable t' find nosecone. Begad! Low powered flight with video camera in t' body. Two misfires with igniter before successful launch.
