Would anyone suspect, as I do, that this was not an isolated incident where the boss simply decided not to go, but the straw that broke the camel's back?
Has anyone considered that, for example, this guy had had the door seal or the TCAS DDR'd previously on the aeroplane and was fed up of it not being fixed? Maybe there were things inop on the aeroplane that he didn't actually include in his reasons for refusal, but were between them enough for him to say 'enough is enough'?
I reckon this sounds like he could be an exasperated captain making a stand against an airline that, in his opinion, is heading for disaster, and as usual the only people that see it coming are the guys who fly the things every day.
