We all know that pilots are for the most part sterling characters, but they are still human.
I don't think that Capt Renslow was a sterling character. This guy had started his airline career flying for Gulfstream airlines on the B1900.
This is an airline where you pay them a huge amount of money for training and work for free. Says quite a bit about him I'd say; what a tool. Perhaps if he'd worked an instructor rather than paying to fly he might have been able to afford to rent somewhere to sleep rather than camping in the crew room. If he'd had a good nights sleep he would probably have remembered to push the power levers forward after dirtying it up.
Colgan Airlines pilots complain about the conditions in their company and not being able to call in sick. Yet when it came to the crunch they voted to reject ALPA membership!
