Kitty Hawk’s Flyer personal VTOL has now flown over 25,000 times

I know these propellers [0] are maybe 1/4 to like 1/8th the size of those shown but thee 56g weight surprised me a lot.

Not only that but my understanding is that when carbon fiber breaks it explodes into a mess of tiny strings. Which is very unlikely to kill you directly though it might get wound up in the other three props and bring the whole thing crashing to earth.

I could see the advantage of these in swamplands or the 'bushes' if you will (places like remote parts of Africa, South East Asia, parts of the Southern United States, Alaska, come to mind).

But the practical use case I can't seem to envision yet. However, if the goal is to be able to fly these things like helicopters but get some sort of massive fuel advantage out of it, I could see them being used for certain types of deliveries if they can hold a substantial amount of cargo via an attachment or something.

I think the advantage is, primarily, that you can pretend that you are pod racing. Minor caveat, the top speed currently seems to be 20 mph.

I suspect this is purely for liability reasons.

That sounds like the current use case for helicopters.
