An in-depth look at the technology conceived or developed by America's first billionaire. A passionate aviator, Howard Hughes built and flew planes that broke speed records, and developed war machines, spy aircraft, and commercial airliners. Despite the impressive heights reached by his technological empire, his health and mental well-being were fragile. During his last years, he wasn't seen publicly or photographed, rarely left the hotel suites he occupied, and was terrified of germs. But when Hughes died in 1976, he left a huge legacy in aviation and technology. When we board an airliner, view TV via satellite, or marvel at America's military might, we might do well to remember the risk-taker who flew faster than his peers and was at heart an aviator obsessively dedicated to both the art and science of flight.
