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