A ground crew member with China Eastern Airlines was killed in an accident Tuesday at Shanghai’s Hongqiao International Airport, the company said in a statement.

The incident happened at around 9 a.m. when an aircraft-towing vehicle ran over the staff member on the tarmac, according to Sixth Tone’s sister publication The Paper. The man was immediately sent to a local hospital, but doctors weren’t able to save him.

China Eastern Airlines said it will “take care of” the deceased’s family, without elaborating, and investigate the cause of the accident.

After analyzing the video footage, aviation insiders told The Paper it’s difficult to say why it happened. In the video, the man can be seen walking as the vehicle rams into him from behind.

Online, many are mourning the death of the China Eastern employee, whose identity has not been disclosed. A related hashtag on microblogging platform Weibo has been viewed over 14 million times.

“I have a family member who works as ground crew at an airport — they’re the ones who guarantee the safety of the aircraft,” wrote one Weibo user. “There should be an accident analysis soon, as well as specific solutions to prevent this from ever happening again.”
