Planes in near-miss over France
Swiss and Dutch planes came as close as 15 seconds to colliding over France on Wednesday, airline officials say.
The two flights were reportedly within 300m of the other when pilots and onboard warning systems averted a crash over the northern city of Rheims.
Rheims air traffic controllers were in charge of the planes, which were flying at a reported 9,500m.
France has launched an inquiry to find out if human error or technical failure was to blame.
A French aviation spokeswoman said the near-miss was not related to the three-day strike by Paris air traffic controllers - which has just ended.
