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. But alas, t' rocket landed on t' videocam and busted it open. Well, blow me down! File recovery attempts failed. Avast, me proud beauty! Here be t' video from t' ground.
