When he saw a man fall into the path of a New York subway train, Wesley Autrey did not hesitate.
The 50-year-old building worker jumped down on to the track and tried desperately to haul him to safety.
But the man, who had suffered a seizure, struggled. And as certain death roared towards them, Mr Autrey made a decision of breathtaking courage.
Instead of saving himself, he pushed the man down into the space between the tracks and lay on top of him, wrapping his arms and legs tightly around him.
With the train just feet away, he told 20-year- old Cameron Hollopeter: 'Please sir, don't move. If you move, one of us is going to lose a leg or die.'
Next second, the first carriage thundered over them before the train screeched to a halt. On the platform, Mr Autrey's two young daughters were among the crowd who had seen the heart-stopping moment and feared the worst.
Then Mr Autrey's voice rang out from below, calling for silence. And as a hush fell, he shouted: 'Tell my little girls that Daddy is okay and the man is okay!' Delighted onlookers burst into applause.
"The presentation or 'gift' of the Holy Ghost simply confers upon a man the right to receive at any time, when he is worthy of it and desires it, the power and light of truth of the Holy Ghost, although he may often be left to his own spirit and judgment." --Joseph F. Smith (manual, p. 69)
