evidence: I am Colonel Li, Commander of the airbase in Changzou, where the military flight training academy is located. On October 19, 1998 four radar stations in Hebei Province reported the presence of an unidentified "blip" hovering over the academy. After ascertaining that the intruder was not a military or civilian flight, I ordered a Jianjiao 6 jet fighter to take off and intercept the UFO. At least 140 people on the ground saw the object. To observers at the base, the UFO first appeared to be a small pointed star, and then grew larger and larger, perhaps as it descended to a lower altitude. Witnesses described an object with a mushroom-shaped dome on top and a flat bottom, covered with bright, constantly-rotating lights. The crew of the Jianjiao 6 interceptor consisted of a pilot and a radar officer. The two officers reported that the object clearly resembled depictions they had seen in foreign science fiction films... When they got within 4,000 metres of the UFO over Qing county, it abruptly shot upwards, easily evading subsequent attempts to get closer. The flight crew reported that it appeared to be toying with the plane by repeatedly outdistancing it and then reappearing right above it. The pilot requested permission to fire on the UFO with the plane's automatic 20 mm cannon. I denied this permission to shoot, and told him to continue to pursue and observe the object. The pilot broke off pursuit at an altitude of 12,000 metres when the plane began running low on fuel. The UFO then apparently disappeared before I could order additional planes to be sent to the area.
