I'm afraid it really is as simple as "it's their trainset". If your, or my, employer wants you to fly the jet everywhere with 10 degrees left wing down, dressed as Ronald McDonald, whilst singing the Yellow Rose of Texas on the PA, and it doesn't contravene any CAA rules....then I'm afraid that's how it's got to be.
Having spoken to a few of our F/O's about this case, I'm afraid the gentleman concerned seems to have lost all sympathy when he tried to shift the blame onto his co-pilot. What ever happened taking responsibility for your own actions?
BTW, anyone know why he chooses not to call himself "Paul" ???
