Very nice. I have somewhere the book Airship Technology, which I bought when I was curious about the possibility of blimp drones (I was an aerospace engineer some time ago). I'm glad you are considering smaller blimps, I think previous projects have been too ambitious. Since I have worked on drone navigation I'm curious about your approach in that regard and how you are going to attain autonomy and get it certified. If you manage to get it a completely autonomous and certified that alone will be an asset even if you pivot away from blimps! Are you going to use alternatives to GPS? GPS is very precise when it works but I doubt you can get certification based on that alone.
