Why was this poor guy doing this? Most probably because he didn't get a chance any other way, namely not in Germany. The situation hasn't changed, even when the demand for experienced skippers was high: you can have thousands of hours in command on small jets, ie Embraer, CRJ and then you do a widebody typerating, lets say on B 747 or A 340, but as a First Officer. If your company doesn't upgrade you for any reason, you can have 10000 hours on type but you will never slide into the LHS with another carrier, because they always require 500 hours PIC on type.
So these are the options: go back to small jets and lousy conditions, stay trapped in the RHS forever or cheat.
I really would like to know how many commanders are flying around without the correct credentials, but with far more experience than the lucky ones. Same goes for surgeons in hospitals, and so on.
