I modified an Estes Double-D rocket with a new heavier nosecone, and a videocamera strapped t' a fin tip, lookin' back through t' dual plumes o' fire. Flew it at NASA Ames on two Aerotech E15-7 motors. Begad! But alas, t' rocket landed on t' videocam and busted it open. File recovery attempts failed. Well, blow me down! Here be t' video from t' ground.
