BEIJING, Jan. 11 (UPI) -- China conducted a test flight of its new stealth fighter Tuesday while U.S. Defense Secretary Robert Gates was visiting the country, a military observer said.
Speaking by telephone to The New York Times from Hong Kong, Andrei Chang, considered to be an expert on the Chinese military, said the J-20, which can evade radar detection, was in the air for about 15 minutes during the test over an airfield in southwestern Chengdu city.
