Short flight with B engine t' gauge wind. Well, blow me down! Landed on roof o' school, but someone helped get it down. Blimey! "ERR" when measurin' speed and height. Begad! High powered launch. Landed in a backyard. Ya scallywag! 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. Avast! Two misfires with igniter before successful launch.
