The crew stopped the climb and returned to Chengdu for a safe landing with a "slightly rearranged radome".
The pilots flying the airplane contacted the control tower requesting an emergency landing due to "mechanical failure" but these images taken by a passenger tell a very different story. In these images the damage to the airplane is visible, as the nose of the aircraft shows evidence of a collision, the question here is, with what did this Boeing 757 collide at 8000 meters? Is it possible that an UFO made contact with this airplane?
Airport authorities immediately opened an investigation and surprisingly came to a conclusion that Air China's Boeing collided with an "bird" at an altitude of 26.000 feet. What type of bird would have caused this amount of damage and survive the collision, since no blood nor any other kind of evidence is visible suggesting that it was a bird that collided with this Aircraft.
Post flight examination raises the suspicion that the aircraft may have collided with a foreign object, a bird strike was ruled out however due to lack of blood, feathers or any other bird remains.
