Back in the early 80's I knew of several TOY shoulder-fired simulated-bazookas with a "flour payload" using model rockets with D12 motors. Some had stick-stabilization (lousy on a horizontal plane), some had fold-out fins, and some had stubby fins. The folding-fin ones flew fairly straight. NONE of the launches were anywhere near vertical nor did they resemble anything close to the safety code other than most were electrically launched.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !
