Let’s not forget that after this project failed, one relevant military contractor found a private buyer for some offshoot projects, like the batarang, bat tracer, and bat suit. They eventually did develop an unrelated “bat bomb” as well, though less aptly named than this original. 
Seriously though, I love stories like this. They help combat our tendency to really, really underestimate how non-obvious it is, beforehand, what ideas will work and how many off the wall ideas you have to try to find the good ones.
