Everyone wore Aviators in Close Encounters of the Third Kind (1977), Dir Steven Spielberg
At the end of Close Encounters, as the drama enfolds, more and more of the scientists/boffins resort to wearing Aviators to accentuate their shock and awe. By the time the space craft door opens the human cast have started resembling delegates at a Top Gun convention. You do wonder whether the US government hands out free pairs with every Christmas bonus.
No global earth shattering event is too overwhelming when you protect your eyes with a cool set of Aviators.
