As far as I can recall, "ghosters " went out of fashion shall we say sometime in the late 80's, and I could be wrong here with the dates when the CAA decided to let it be known they "weren't happy " with the practice. …..which had taken them a rather long time as we know to arrive at this decision.
I'm aware of Ghoster's being worked much more recently so the transport industry opt out from EU Working Time Directive obviously allows this!
