From 1996 to 2001, Boeing and Lockheed Martin produced rival designs and prototypes for the Joint Strike Fighter, a stealthy, affordable combat plane intended for the 21st century needs of the U.S. Air Force, Navy, and Marines. In "Battle of the X-Planes," NOVA goes behind the scenes to show the world's newest fighter taking shape, as Boeing and Lockheed Martin compete to win the largest contract in military history.

In the final months of World War II, American troops discovered a top-secret facility in Germany with an advanced batwing-shaped jet fighter. If Nazi engineers had had more time, would this jet have ultimately changed the outcome of the war? In this National Geographic documentary they rebuild a jet discovered in a top-secret German facility during the final months of World War II - the Horten 229.

A group of fossil hunters uncover not only the bones of a 77 million year old dinosaur, but its mummified and fossilized 'body'. After excavating the duckbill nicknamed 'Leonardo', scientists begin a battery of tests including a radiographic autopsy. Journey along with a team of paleontology experts as they make several astonishing discoveries including the creature's last meal and never-before-seen internal organs.
