Speaking to RT in Doha, the former pilot said Flydubai’s top management was aware of the issue, but had done nothing to resolve it. “When I was still at the company, one of the last things I told management is that there would be an accident because of pilot fatigue,” he said.
The reason for fatigue is simple – pilots are being repeatedly overworked and not given enough time to sleep between flights.
