Delta Airlines flight DL-8957 was intercepted by two Greek F-16 fighter aircrafts on May 19th.
According to the airline, the radio contact with Greek ATC was lost for a brief period of time when the Boeing 767-400, en-route from Frankfurt, Germany, to Kuwait, was transiting through Greek Airspace.
The fighter jets returned to the airbase as the communication was restored.
The flight continued to Kuwait.
