The Catalina landed in the vicinity of Gublusk Bay, Lower Lough Erne, turned into wind and shut down its engines. It then drifted back into a yacht causing damage to the Catalina’s right elevator. Despite a pilot’s briefing, different expectations remained between the Catalina crew and marshal boat crews as to how the Catalina was intending to moor up, with the Catalina crew expecting that after they shut down the engines a “tug boat” would tow them to the mooring, and the marshal boat crew expecting the Catalina to taxi to the mooring under its own power.
