AirAsia Flight 8501 did not have permission to fly to Singapore on the day it crashed into the Java Sea, transport officials have said ...................
However, the company was only authorised to fly that route on Mondays, Tuesdays, Thursdays and Saturdays, Indonesia’s transport ministry said.
"It violated the route permit given, the schedule given, that's the problem," Djoko Murjatmodjo, the head of air transport, told AFP on Saturday.
It was not immediately clear why AirAsia had been flying that day if it did not have permission. All the company’s flights from Surabaya to Singapore have now been ordered to stop. The transport ministry has announced a full review of all AirAsia flights.
Presumably a flight plan was filed so I do wonder how the (supposed) breach of operating permit can be deemed as 'the problem'.
