We have seen this before many times in history of personal flight. The first one was the Hiller VZ-1 Pawnee in 1955. It seems that there is something called the Ground Cushion Effect that makes it hard to rise above a few feet. Franky is a genius but no one has succeeded in making a true high Flying personal lifter. The best you have is a Hovercraft without a Skirt. I have been working on this idea for years and so have some of the great minds of our time. If Franky pulls off a true Flying platform and is not afraid to fly it i will be amazed.
