An unidentified object exhibiting extraordinary flight maneuverability hovered over China's ninth-busiest airport during the evening, severely disrupting civilian aviation. Flight controllers visually and instrumentally detected the object and subsequently delayed or rerouted 18 commercial flights as a strict safety precaution. Chinese military authorities did not publicly disclose any explanation. Several days later, state media floated a partial account suggesting that a military aircraft conducting an unannounced test flight had been responsible for the closure, but full details were never released. The event drew international attention as one of the highest-profile aviation disruptions ever attributed to an unexplained object and remains officially unresolved in publicly available Chinese records.
