The NTSB's narrative final · quoted from the NTSB record
The pilot said the airplane was high and fast as it crossed the runway numbers. After touchdown and application of reverse thrust, the pilot did not like the runway remaining, so he added power to abort the landing. It took the engines 1 to 2 seconds to spool up, and he decided that it would be better to roll off the end of the runway than to attempt a takeoff with so little runway left. He went back into reverse thrust. He did not apply full brakes, as he was concerned that the airplane might flip over. The airplane went off the end of the runway, and slid to a stop in snow and mud. The nose gear collapsed in the process, and the airframe sustained damage in the wheel well area.
