About all the mess that went on at that station just to get off the ground. That's enough in itself. I had a similar situation minus the runway incursion. They promised the world about a plane that was brought to us at an out station. The pc air was fine, they wouldn't pull the air early, etc etc. Wrong. If you want to work in stagnant air heated to 90+ degrees, be my guest. I'm no hero, and I certainly don't want to subject my passengers or crew to that as well.
