BEWARE: There seems to be a recurring problem with cockpit windows being left unlocked on some airplanes, especially in PHX. You won't notice it until takeoff, at least that seems to be the intent.
Also, there are reports of shoe polish being put on cockpit headphones. There are also switches not normally moved that are deliberately being placed in abnormal positions. In other words some strange 'practical jokes' are being played on east pilots by someone.
Check your 'six' because someone may be out to get you.
Had that problem a couple of years back. Many switches out of position. Solved that problem with a very long cockpit prep which delayed several flights. I had reported this to the company but did not get the desired results until the airplanes were late due to the long check and consultation with dispatch and maintenance.
All the best,
Bob
