On Jan 13, 1982 an Air Florida Boeing 727 crashed into the Potomac River in Washington D.C. 73 of the 79 people aboard were killed instantly, leaving 6 survivors in the freezing river.
He gave it to another survivor.
He did this FIVE TIMES, reaching the rope that could save him, and giving it to another.
Because not once, not twice, but all five times, he gave the rope to another, so they could live.
What he did was not duty. It was moral HEROISM.
It was action, as we rightly say, above and beyond the call of duty.
