Yes. And what the OP is proposing is not among them. Here, I think, is the OP's inspiration David Windestal is the knucklehead (and I use the term "respectfully") who launches (sugar) rocket-propelled knives at things. The OP is coming to this project after seeing somebody do a YouTube stunt; the entertainment value of which is that it is stupidly dangerous and poorly executed. The posts in this thread pretty much add up to the disclaimer that Windestal ought to have flashing along the bottom of his videos in a perpetual crawl: "DON'T TRY THIS!" The OP is getting the same kind of advice (expressed stridently or pleadingly) he'd get if he asked about building a mortar, or a manned rocket glider, or any other thing that falls this far outside the safety codes for rockets that go up.
