During the Cold War, Colonel Kenneth Collins regularly flew the world's fastest planes from Groom Lake at Area 51. He has experience flying through three wars and helped develop spy planes such as the original A-12 and SR-71 in their infancy.
For decades Area 51, the top secret air base the government used during the Cold War, was a source of urban legend. Space aliens, unidentified flying objects, secret weapons - they were all part of the lore of that black hole in the Nevada Desert just north of Las Vegas. Now the National Atomic Testing Museum has an exhibit about the dark secrets of the desert. We talk with the creators of the exhibition.
