Again what this shows is that it is all a question of standards. I don't think uniting unions worldwide to villify self sponsored pilots is the answer to this problem. It is not the unuions who hold ultimate responsibility to maintain standards. This is a job for the regulators and this is where the pressure should come from as they operate irrespective of economic pressures. As in any other profession if you put in place and police high enough professional standards then you should stop the less than marginal cases from making it through.
