The U.S. capital boasts many memorials, but none with a more bizarre history than the obelisk erected to America's first president. Over 55 stories high and weighing over 90,000 tons, the Washington Monument stands stalwart in the city's center. From concept to completion, it took 100 years--years filled with mystery, ceremony, conflict, government action, and inaction. Proposed in the late 1700s by a group of prominent citizens and finished in the late 1800s by the Army Corps of Engineers, the exterior is mainly Maryland white marble, while the interior is made of granite, iron...and a few surprises. How did it come together and why did it take so long? Historians tell stories of stalling bureaucracy, secret societies, and triumphant engineering. Stark and daunting on the outside, we let viewers know what's inside.

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.
