Circumstances:
The approach to Thessaloniki Airport was completed in poor weather conditions. The aircraft landed too far down the runway and after touchdown, the crew realized he could not stop the aircraft within the remaining distance so he decided to veer off runway to the right.

- Poor weather conditions,
- The runway surface was wet and the braking action was considered as moderate to low,
- The flying crew consisted of two highly experienced captains,
- The crew was under stress during the final approach due to poor weather conditions,
