I'm admittedly interested in what can be done today versus after new regulations that could take years, or decades.
In my case in particular, my primary focus is on an airplane that flys horizontally, intended to fly under the same rules as any aircraft and pilot with a PPL, but happens to land without a runway. I'm not really interested in straight-up "drone" style flying, but the fact that such flight characteristics are needed to land my plane VTOL... this has to be taken into account by FAA signing off on it.
Here is one example of eVTOL (full on manned "drone"), happening right now. These guys seem a little ambitious, but they intend to do manned flight next year in California. I do wonder what analysis on this topic I have raised that they have done. Maybe their aircraft would technically be ready, but what about legalities?
