Excluding the technical and operational aspects of this event, asking/ordering journalists to stop using cameras, whether allowed or not is a pointless thing to do. The first job of cabin crew is to ensure the safety of the passengers. Their time might have been better spent thinking about how to execute an evacuation. And let's remember, the culture of a company is expressed in the actions of its employees. The world in which we now live is recorded in detail. Nothing we say or do will stop that and it is naive in the extreme to think otherwise. Therefore, to avoid harsh judgement by social media, make sure you have a practical and common sense approach to dealing with the inevitable problems we face doing our job. A good start might be to stop your senior executives saying that serious events like over-runs are a common event. So unless we can uninvent things, let's learn how to deal with the world as it is.
