When the program makers do not provide the public with full information then I can only mistrust it.
No programme makers do that. There isn't time for a start. You have to trust both them and the regulators that you are being told the truth.
At the end of the day the programme was saying that many RYR pilots are unhappy with the 'safety culture' of the airline. This seems to be borne out by many other sources.
Despite your 'conspiracy theory' about the Ryanair Pilots Group, can you name me another major airline that has such an orgainisation set up for its pilots to allow them to express their concerns free from harassment by their management?
