Narrative:

The problem or incident that occurred was that our citation ii slid off the runway. The nosewheel, by about 1 ft. It happened when we were cleared for takeoff. The captain gave a little power to start moving. We had to make a right turn to line up with the runway 16. I was calling off the final items on the checklist when I heard him yell. I looked up and just saw that we were moving towards the edge of the runway. We had no braking action and just slowly slid forward. We finally came to a stop with the nosewheel about 1 ft over the edge. It was hard to see, everything was snow covered. We called tower that we were stuck. The airport authority/authorized came out and mentioned that the reason the ice and snow was being so slippery was that the snow which fell earlier that day, had frozen on impact. After about 5 mins, a tug had arrived but it couldn't do any good due to the snow. About 9 persons pushed the plane back by hand and swung it around just by pushing on one wing and holding the other. In the process, several people slipped. One was a mechanic and saw no damage. We taxied back to our hangar where he had a closer look. The chief pilot called the airport for sanding at the approach end of runway 16. This was done. After being deiced a second time, we taxied out and continued our flight.
