Narrative:

I lined up and attempted to take off from a taxiway located between phx airports runway 7L and 7R. My takeoff clearance was canceled by an alert tower. My backgnd: I'm a trained military mishap aircraft accident investigator. I have been going through my mind what factors would lead me, a conservative, by-the-book pilot, to line up on a taxiway in daylight? I crossed runway 7L getting clearance from tower to position and hold. Captain was entering data in FMS. I felt rushed as plane was approaching to land. I have received superb training, and work for a safe company that stresses safety, crew procedures, etc. I suspect the main factor was long term fatigue which prevented me from breaking the mishap chain as I allowed myself to become rushed during the last min before entering the phx taxiway. The captain also is experienced. Only the alert phx tower stopped us.
