In the early days of Ryanair, when simple competition was enough.  A variety of aircraft parked at the DUB freight ramp; a British Air Ferries Viscount, a 748 to the left and a TNT 146F, British registered.  The integrators had yet to establish their own dedicated fleets so contracted any cargo capacity they could get their hands on.  This meant that many cargo ramps were occupied all day by ad hoc freighter aircraft.
