All right, it's not exactly the jet-pack we've all dreamed of, but this is a totally awesome flying machine all the same. It's a Hiller Flying Platform, developed in the US from about the 40s on, but never actually put into production. You can imagine how they might think we'd have developed something pretty sleek and shiny by now, if that was the stage they were already at. But we haven't. Instead we have an Internet, but what sort of consolation is that?
