An unidentified flying object was spotted descending vertically in the sky in eastern China.

The video was filmed in Shanghai on September 1.

According to eyewitness Mr. Li, it appeared to be in a descending state, unlike an ordinary aircraft, with a vivid and radiant red hue, somewhat reminiscent of Monkey King’s somersault cloud.

In response to this event, the China Meteorological Administration's Public Meteorological Service Center suggested it resembled a "contrail cloud from an aircraft." The Shanghai Meteorological Bureau also speculated that it might have formed after the dispersion of a contrail cloud.

Shanghai Meteorological Bureau expert Wu Rui explained that, based on the images provided by citizens, the possibility of it being a contrail cloud seemed more likely. However, precise astronomical assessments would require additional evidence, such as confirmation from relevant aviation authorities regarding flight paths over Baoshan at that time.

9月1日傍晚，上海宝山区，在火烧云映照的红色天空下，有不明飞行物垂直坠落。据目击者李先生称，它是一个下落的一个状态，不像是飞机，颜色明显很亮很红，有点像孙悟空的筋斗云。
对于此事，中国气象局公共气象服务中心回应称，认为像是“飞机的尾迹云”；上海市气象局也推测，可能是尾迹云扩散后形成的。上海市气象局专家邬锐介绍，根据目前市民提供的画面，尾迹云的可能性较大。不过，严谨的天文判断要更多证据，比如需要航空等相关部门确认当时经过宝山的航线。
