Airline staff have revealed the cause of the disaster
The translated article that Kulverstukus provided, and commented on by Air Scotia is difficult to accept in its entirety, but after numerous reads I feel there may well be some validity to it.
It brings to question the safety culture within this airline. Issues such as training bonds, defect reporting, inexperienced cabin crew, all driven by an extreme low-cost, possibly almost bankrupt airline are certainly ingredients not to be overlooked by accident investigators.
