Frank...no it usually is the Devil.
CXorcist...couldn't agree more. A what if on the QNH as you line up for departure is nothing less than intimidation.
Must also agree with one of the earlier posters (as much as I am enjoying identifying all the plonkers) that a majority of checkers are not as portrayed here. Sadly many of the good ones have opted out of the system and form the backbone of the training system...namely line captains.
There were some worse plonkers back in the old days...I am reliably informed that one of the F/O's got back to his room in Singapore (in the 80's) with his prey to find that the skipper hand gained entry and hoofed the contents of his nav bag into the bath after having thoughtfully run it for him. Hell hath no fury as they say.
