Narrative:

I was riding as a passenger in a king air that skidded off the edge of the runway. I was in the front seat. The captain who has considerable king air time forgot to unlock the left propeller of the garrett pwred B100. On the takeoff roll he brought the left propeller into reverse to try to unlock the propeller. The right engine was still up on power. The aircraft went hard left and went off the runway. Both propellers were bent. There were no injuries. The pilot was in a rush and did not do the checklist. There were also several vehicles near the runway which probably distracted the pilot. We were at an uncontrolled airport with no supervision on the ramp area. Several of the vehicles were waiting for another aircraft with a landing gear problem. I am a pilot but was just a passenger on this flight.
