Roswell Martians Might Have Been Nazi Kids From Mengele’s Lab

Area 51, a U.S. military installation in the Nevada desert about 75 miles north of Las Vegas, has attracted rumor and speculation for decades, fed largely by the government’s refusal to discuss exactly what goes on there.

In “Area 51: An Uncensored History of America’s Top Secret Military Base,” journalist Annie Jacobsen tries to get to the bottom of these secrets. What she comes up with is an informative history of Cold War spy planes sandwiched between an outrageous -- and thinly sourced -- tale involving Josef Mengele, Josef Stalin and flying saucers.
