I'm pretty sure Capt Goss knew exactly what he was doing by going to Channel 4 with all the allegations. He would have worked at this for sometime and would realise the consequences of his actions. He would have documented the evidence even though Ryanair have threatened legal action. This would have not been done on a whim unlike some of the comments on here. He had a senior position with the company and realised he would probably loose his pension (if he had one). If he firmly believed in 'telling all' I'm sure he would have expected to be fired as a result.
