Reality check
One cannot destroy someone's livelihood and expect to be welcome. Yes it is tough but the nosewheel incident is a common but avoidable accident. We can all make mistakes but we also have to pay for them. Put yourself in his shoes. Some schools only have one main aircraft to train on and if it is down revenue is lost so the cause of the loss must be isolated and dealt with. It's nothing to do with flying just plain ecomomics and human behaviour.
