Latkowski's claim that Protasiuk declined to fly to Severny because of the weather and had to be ordered to do so does not correspond with the MAK report.
According to MAK the flight departed without the crew obtaining a METAR or TAF for Severny. Even if they had obtained a forecast it would have been wrong. The fog took the forecasters by surprise. Its severity did not become apparent at Severny until shortly before the time the flight was getting airborne. The crew found out when en route.
Protasiuk may have made some representations about the lack of a valid destination forecast. He would have been entirely right to do so. But we don't know this happened.
