Facts:

The respondent was a senior captain in the employment of the appellant. On 1/2/98, he and a co-pilot were scheduled to fly a DO 228 aircraft when an incident occurred. After starting one of the engines the aircraft suddenly began to roll forward and all efforts to stop were to no avail. The respondent was eventually able to manoeuvre the aircraft to a stop thereby avoiding colliding with another aircraft, which was parked directly ahead of it. In the process however the right wing tip of the aircraft hit a flag pole resulting in some damage to the wing tip bulb.
