Headlines are so sensational. From the article:

A Korean Air spokesperson said: “A Korean Air aircraft came into contact with a Cathay aircraft during pushback at New Chitose (Sapporo) Airport by the third-party ground handler vehicle which slipped due to heavy snow. There were no injuries and the airline is cooperating with all relevant authorities.”

This was not related to the other event, at all. A plane slid into another, due to heavy snow, while being moved by the ground crew.

Headline totally made it sound like two airplanes flew into each other mkd air lol

“Two planes collided on a runway in Japan” is terrible journalism. This was not on a runway, this was during the pushback at the gate.
