National Geographic Top Secret Plant 42

Step inside Plant 42, America’s clandestine 'black world' of off-the-record projects developed in secret. Hosted by Jake Ward, editor of Popular Science, the program explores little-known initiatives that are so confidential some are said not to exist. From futuristic aircraft capable of speeds faster than the speed of sound to stealth weapons and propulsion systems, Ward pursues every angle—on the record and off—to take audiences as deep inside the secret site as possible.
