It seems you are goading for a fight Yamaha........ £40k for our skills and education is below par. I would hazard a guess that you have not had your hand in a waste tank at 4 in the morning trying to remove an airfreshner that a hosty unwittingly put down the lav, knowing that the fair paying public arrive in a hour to fly off on holiday. And another thing, it should not affect your engineering proffessionalism whether their are two military pilots sat on bang seats or 800+ 'civvies' flying half way across the world, well it wouldnt affect my professionalism....................
