Images of a Chinese Fighter Aircraft emerge:
Images have emerged on Chinese defence sites that appear to show a new Chinese fighter aircraft in flight.
The flight was said to be the first conducted by the aircraft that is now being commonly referred to as the Shenyang J-31. Previous reports have variously given the aircraft's designation as the J-21, J-31 or F-60.
Images for the aircraft first appeared in mid-September 2012 and were said to be taken at the Shenyang Aircraft Corporation airfield.
