Cangzhou air force pursuit
Radar in Hebei tracked an object over an air force training base near Cangzhou, and Chinese fighters were sent after it before it climbed away.

The account
On 19 October 1998 several military radar stations reported an unidentified return over the Cangzhou area. Witnesses on the ground said they saw a large lit object, and a pilot quoted in the press said that as he closed to about 4,000 m it shot upward; two fighters had to return low on fuel. The story ran in the Hebei Daily and was picked up by the South China Morning Post.
The sceptical view
Details come from press retellings, which disagree on the time of day and number of witnesses; no radar data or official report has been released.
The researched reading
A promising multi-witness, radar-tracked case known only from inconsistent press accounts. A balloon, aircraft or secret flight is likeliest, with modest room for something unexplained.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 35% | Balloons, aircraft and bright planets have caused many military intercepts. A pilot losing an object that climbs away fits a balloon or a high, bright planet seen through haze. |
| Secret human technology | 18% | A foreign reconnaissance flight, a balloon or a Chinese test craft over a training base would explain both radar tracks and the scramble. |
| Genuinely anomalous | 15% | Several radar stations, a pilot and over a hundred ground witnesses is a strong combination if accurate. However, no data are released and accounts disagree even on the time of day. |
| A known natural phenomenon | 8% | Anomalous radar propagation can create tracks that fighters then chase toward unrelated lights. |
| Perception, memory or mind | 8% | Ground witnesses, primed by the commotion, may describe a large lit craft from ordinary lights. |
| A poorly understood natural phenomenon | 6% | An unusual luminous phenomenon cannot be excluded. |
| A hoax or fabrication | 5% | Press retellings added colour, names and details, and some versions cannot be traced to the original Hebei Daily report. |
| Undetermined | 5% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
Official position: Chinese press said local departments were investigating; no official report or radar data was released.
