China's J-20 stealth fighter prototype had a second test flight on Tuesday at the Chengdu Aircraft Design Institute's airfield in Sichuan Province, according to witness accounts.

"The J-20 made several passes and waggled its wings (rolling the plane first to one side then to the other) to salute the crowd near the airfield," a witness told the government-owned newspaper Global Times.
