You know, the unmanned drones the military’s going gaga over. Apparently, you can download all kinds of details about them here. I haven’t yet attempted it because the website’s strangely laid out, but from what I’ve been able to figure out, it looks like you can download papers (in PDF format) on the various subsystems on an individual basis. (I hope to Og the embedded link works, it was a royal pain for me to get it to work on my box.)
