Ok, revoking, suspending or any other certificate punishment is not even close to being warranted because even though the root cause was the action of this pilot, there were some pretty compelling reasons why this was going to happen to someone. It was only partly to do with the attentiveness of the pilot and punishing this person is flat out wrong unless she was doing something so egregious that firing her was the only safe option and that would require a history of incidents and remedial training. In this case I can say with 100% certainty that she will be more careful than most when approaching an LZ. If this person had a good record then punishment is not as smart as some extra training and if you do that, whamo you have a better employee than if you took on an unknown quantity or someone with less experience.
