I wonder if this relies on ground-effect for lift? Didn't someone make a drone that could carry a person? And then there is the "hoverboard" that self-balance and carry a person, so it is practically a drone if someone just added a remote - though it doesn't do altitude. Ha, check out the human-sized drone at the bottom of the article: http://www.engadget.com/2016/01/06/184-delivery-drone-for-people/ http://www.engadget.com/2016/01/06/184-delivery-drone-for-pe... Can it still be called a drone when there is a human onboard piloting it? I guess not.
