Ducted Fans Hulka, that is the solution to liability. However you can design something to be idiot proof and usually a bigger idiot comes along.

The most clever VTOL I think I have ever seen, and electrics make it happen. Notice the doors that uncover the front two lift fans and the rears rotate 90 degrees. It's speed advantage being a flying wing / blended wing body would be a huge benefit. It needs a way to deal with "deliverables" but I'd rather not go their.

Yes, seen something like that. Wonder why “they” are testing standard drone platforms that are clearly dangerous for day-to-day use. The example you provide is clearly much more safe.
