oh no! you were all tired during the exam??
hope you still passed! 
Being tired (fatigue) effects vision. Not much sleep for a few days plus putting in a day's work isn't condusive to not being fatigued. Did pass though, but didn't really enjoy the eye test.
Mechanic with the room mate's company found out that towing a cheyenne with a tow strap attached to a forklift with no one inside the airplane is a bad idea.
Bonus: dedicated Lifeguard medivac cheyenne the company operates and *was* on alert 24/7 for air ambulance flights (remember, a lot of no road areas in Alaska). Guess it's a good thing that they have kits to make most of their navajos into temporary air ambulances. Oh, and it was during the middle of the night that he did this.
