I meant of course follow ATC commands, which this pilot refused to do and is now facing harsh punishment. He/she continued with the landing against ATC's wishes and got in the way of the Mayday aircraft in the process. Prevented the Mayday aircraft from landing a little bit sooner.
To repeat my thinking:
1. yes it was wrong to continue the approach and get in the way of an aircraft that has declared Mayday (for whatever reason good or unfounded).
2. yes he/she should be punished (although I believe this particular punishment to be unduly harsh).
3. just a general question: in what situation or situations can a pilot not obey ATC ?
edit: in this case pretty clear, abandon approach and give way to Mayday aircraft. But in other less critical ATC demands , is it possible for Captains to have any say?
