I think this the offical report of the J-10 crash on Sep. 4th in Guilin.
"Bird strike at low altitude. Wang Jiandong, a pilot of an Air Force brigade in the Southern War Zone, calmly and accurately placed ground damage to a minimum." "Follow-up investigation confirmed that the accident happened in the take-off rise, the engine was hit by birds caused by air parking. According to the comprehensive assessment of experts, Wang Jiandong avoided residential areas three times in 37 seconds, and a series of calm and accurate landing places minimized ground damage and did not cause casualties."
