Flights grounded in Greece after radio frequency loss

Athens (AFP) – Flights at Greek airports were cancelled or delayed Sunday after a technical problem knocked out airspace radio frequencies, the country's civil aviation authority said, calling the outage "unprecedented". At Greece's main airport, Eleftherios Venizelos in Athens, passengers were stuck in long queues as several domestic and international flights were delayed or grounded altogether. The radio frequency loss was first reported around 0700 GMT. "No plane landed or took off for at least two hours," said the press office at Athens airport. For up to three hours, most aircraft headed for Greek airports were redirected to Turkey, according to Greek public television ERT.
