    It was rush hour in the morning. Heather Sant, 36, was driving her white 2012 Mazda on the road with her nine-year-old daughter and ten-year-old son in the back. Suddenly, a red pickup truck cut them off. Sant turned the wheel hard to the right, sending the Mazda slide off the road and down an embankment(路堤) that ended in a drop-off after about 50 feet. If the car didn’t stop, it would take off and dive into the road some 20 feet below. Then a bit of luck: as the car raced toward the edge, its undercarriage got stuck, stopping it suddenly.

The people inside, however, were far from safe. The car had come to rest on top of a retaining wall(护墙), balancing on the edge of disaster. One sudden move by anyone inside could throw the car off balance and send it over. Jacob Rodriguez watched everything in terror from the nearby truck company where he works. As an experienced sailor, just like every time he met shipwreck, he whispered a sailing saying “Ship, shipmates, self”, then immediately he and four other men ran to the car. They leaped onto the trunk(后备箱) to balance the weight as the terrified kids in the back seat watched.

Meanwhile, Julio and his nephew Marco, were driving to their jobs at nearby Premier Automotive. Julio jumped out of the car to help while Marco went to the shop, grabbed a strong rope, and returned to the car. He tied the Mazda to an F-350 truck that had been driven over by one of the other rescuers. With the car secured, the group carefully opened the back doors and helped the children out. But their departure shifted the cars weight, causing it to tip forward. The men, still on the trunk, begged Sant to jump into the back seat. She did and then inched out of the back door. Finally, the men carefully got off the trunk. Everyone was safe.

“Another foot,” Rodriguez told USA Today, “and this would be a different story. ”
