China: Mysterious Ink-Like Shadow Filmed Expanding in Shaanxi Sky

On May 6, 2026, in Shaanxi, a video recorded a strange dark shadow appearing in the sky. After a plane flew past, the black shape gradually spread outward above the filmer. The shadow expanded through the sky like spilled ink, creating an unusual and unclear visual effect. It did not immediately resemble a common cloud shape. Chinese viewers discussed possible explanations in the comments. Some guessed it might be a swarm of flying insects, while others questioned whether the video had been made with AI.
