The Stockholm Air Traffic Authority grounded all aircraft on Thursday due to a “network communications” problem.
“No planes are allowed to take off at the moment and we’re taking down the planes in the air,” said spokesman Per Froberg. “It’s a network communications problem.” Froberg declined to provide further details.
The move came just as Egyptian and French officials were informing media that Egypt Air Flight MS804 had crashed earlier in the day in the Mediterranean Sea. No cause has yet been determined for the tragedy.
