It's also a funny story because this is the most popular garage pulse jet design, but it's not really a good design other than the fact it reliably makes thrust and the most godawful noise in the world. It's so inefficient you can see videos of these things literally melting themselves into spaghetti, so I don't know if you're going to get more than a single flight, even if nobody shoots it down.

I suspect somebody is just trying to get their nose in the defense trough.
