When Air Florida Flight 90 smashed into a frozen lake in the middle of a snowstorm, all but six passengers were killed. Some 20 minutes later, a helicopter arrived to rescue the survivors. After getting one man to safety, the helicopter threw a life-ring to Arland Williams who immediately gave it to the passenger next to him. When the helicopter came back for a third time, he did the same thing again. And again. When the helicopter came back a final time, Arland was dead. He’d used his last ounce of strength to save a complete stranger.
