China’s civil aviation authority is investigating an incident at Shanghai Hongqiao International Airport in which a plane directly crossed into the path of another plane accelerating down a runway for takeoff.

Around noon on Tuesday, China Eastern flight MU5643 to Tianjin was in the process of taking off when another China Eastern flight that just landed began to cross the runway. The pilot of the plane taking off decided to go for it anyway, and managed to get off the ground before colliding with the plane on the runway.

A preliminary investigation by the Civil Aviation Administration of China has blamed the near miss on the airport’s air traffic controllers.

China’s ATC have been criticized a number of times over the years for speaking in Mandarin Chinese instead of the standardized English as well as falling asleep while on the job.
