This unnamed pilot was the captain of the priests' flight back from a pilgrimage.
When Noel Furlong took Fintan Fay to see the cockpit, the latter freaked out when he saw his reflection leading to Furlong saying that Fay isn't meant to know he was a priest. Chaos ensued and the pilot urged Dougal McGuire, who was with them, to press the red emergency button.
However, the hapless priest pressed the wrong button which lead to the fuel tanks emptying. Ted Crilly held a competition to see which priest deserved the last parachute on board, until the captain announced that both of them had been taken. In reality, Jack Hackett had left the plane with one parachute for himself and the other hooked to the drinks' trolley.
The captain later came to him asking him if he knew how to fix the fuel gauge. Although Ted
later managed to fix it he freaked out when he realized he was on the wheel of the plane.
