VIENNA/FRANKFURT (Reuters) - Dozens of aircraft briefly vanished from air-traffic control radars in Austria, Germany and the Czech Republic on separate occasions this week and last week, officials said on Friday, adding that they were now investigating the incidents.

Air-traffic controllers in Austria and Germany said data about the planes' position, direction, height or speed went missing on June 5 and June 10, but the outages posed no serious danger to people on the aircraft travelling at high altitude.

A spokesman for German Air Traffic Control said: "Planes disappeared from screens for a matter of seconds, here and there. The outages were sporadic and not grave."

"It must have been an external source of disruption. We are trying to identify the cause," the spokesman said.
