Belfast Telegraph readers have voted Billy Bingham's men's victory over the Spanish in Valencia number one in a poll to decide Northern Ireland's finest hour in sport.
The strike that stunned the World Cup hosts 34 years ago has triumphed over many other wonderful moments, like Olympic gold medal glory and World championship successes.
The line screamed out by BBC commentator John Motson, 'Arconada … Armstrong!' as the Spain goalkeeper put the ball on a plate for the Northern Ireland striker, is still fondly remembered by fans who are old enough to have been watching on that amazing Friday night.
Armstrong couldn't have imagined at the time he lashed the ball into the back of the Spanish net just how much that goal would change his life.
Clubs in Spain took notice and he would join Real Mallorca a year later and he now lives on the island.
Armstrong was back in Belfast last night to take the plaudits once again at the 2015 Belfast Telegraph Sports Awards.
He was joined on the stage by Pat Jennings, Jimmy Nicholl and Martin O'Neill, who all played their parts on the night - Jennings and Nicholl in a flawless defensive performance and O'Neill captaining the team to their greatest moment.
Dame Mary Peters, Jimmy Kirkwood and Stephen Martin may have won Olympic gold and Barry McGuigan and Dennis Taylor been on top of the world, but Gerry's goal-den moment just can't be eclipsed.
