For goalkeepers, one way to tell if you've really screwed up is if fans of the opposing team storm the field, dancing, celebrating what a dunderhead you've turned yourself into. If, in the course of reveling in what a blunder you've made, opposing fans have to be shooed off the field in droves by riot police, you can safely say you've really bit the big one, so to speak.
This goalkeeper in Tanzania knows this feeling all too well.
In the story of Icarus in Greek mythology, Icarus busts his father, imprisoned in a labyrinth, out by flying with wings made of wax and feathers. Icarus' father warns him not to fly too close to the sun or the wings will melt. Icarus flies too close to the sun, the wings melt and Icarus plummets into the sea and drowns.
That's sort of what happened here.
