Of all the "fictional" technologies that enable personal flight, Iron Man's suit is the hardest, and most dangerous, to pull off. Flying with a jetpack is no longer science fiction, and even a hoverboard has made substantial progress. But a jet-powered suit? Hardly. That never discouraged British inventor Richard Browning from trying. And his dedication, and perhaps insanity, has finally paid off. He has become the real-world equivalent of Iron Man by donning a suit that, in practice, puts mini airplane engines on his arms and legs.
