It has been going on for decades, I remember a very senior check CP flying the 757 at a UK charter mob being fired after 15 years of very successful and competent service because it turned out he had faked 'most' of his military hours. Was only rumbled when another military pilot joined and was introduced to the said CP at induction as 'here is someone you will know since you were both in the same squadron!'. Very embarrassing, but by all accounts he was a top bloke and good aviator. I guess what I am saying is that false hours don't automatically mean crap pilot. What it does show is that jobs advertised on 'hours' is very arbitrary when each individual is the person responsible for producing records of those hours, more emphasis needs to be put on competence as opposed to total time.
