Forget China's astronauts. The country's most famous intergalactic traveler lives in the last house on his lane at the edge of a Siberian forest. Meng Zhaoguo's odyssey began at the Red Flag logging camp in the Manchurian province of Heilongjiang, when he saw a metallic glint thrown off nearby Mount Phoenix. Thinking a helicopter had crashed, he set out to scavenge for scrap. The 36-year-old lumberjack stood gazing at the wreck from across a valley when "Foom! Something hit me square in the forehead and knocked me out." That collision four years ago, and what followed, has made Meng a celebrity even today among the growing number of Chinese gaga for little green men. In a country that bans "evil cults" and monitors faith in anything but the Communist Party, a belief in extraterrestrial life is one of the few fringe convictions that's been allowed to grow into an organized movement. The government-approved China UFO Research Center boasted 50,000 members and held annual conferences before splintering into competing factions three years ago.A 20-year-old Chinese bimonthly magazine about UFOs enjoys a circulation of 200,000. "We have so many visitation reports that if people don't have pictures, we won't bother investigating," says Zhang Jingping, director of the Beijing UFO Research Association.
