Well, sort of.

This does bring back memories of my old model rocket days. NOthing *quite* so spectacular, fortunately. We did once have a whole package of class E-engines (fairly good sized, 40 N-sec total impulse) that detonated shortly after ignition. Several other models exceeded the speed of balsa and ended up looking quite a bit like Rubicon I:

Then, there were those black projects that involved combining regular model rockets with signficant quantities of aluminum powder, potassium perchlorate, and fillament tape. I'd say more but those particular launches are still highly classified, not to mention my 5th amendment rights....
