Greek airspace blackout linked to old systems, not cyberattack

An eight-hour radio outage at Greek airports last week that forced authorities to clear the country’s airspace and divert dozens of incoming flights was in part due to an outdated communications system, investigators said in a report.

Flights were suspended into and over Greece on January 4 when air traffic controllers lost contact with most planes, including dozens heading for Greek airports, as radio frequencies went down and were replaced by static.
