A Farman F.60 Goliath passenger plane, operated by Cie des Grands Express Aériens, was destroyed when it crashed following a mid-air collision over Thieuloy-Saint-Antoine, France. The pilot, mechanic and three passengers were killed. Two crew members on the other plane were also killed.

The other plane involved in the collision was a de Havilland DH.18A, G-EAWO, which operated on a mail flight from London-Croydon Airport to Paris-Le Bourget Airport.
Both pilots were using the same railway line in order to navigate in misty weather & poor visibility. They collided head-on at an altitude of 150 m. This was the first mid-air collision involving airliners.
