Incredibly, Joe Berti survived two explosions in the span of three days. He's a witness to the Boston bombings and the deadly West, Texas, fire that exploded at a fertilizer plant.
The Austin resident was competing in the Boston Marathon when the bombs went off. He was running for a charity called "Champions For Children." His wife Amy was just 10 feet from the first blast at the finish line.
The couple couldn't immediately get in touch with each other and feared the worst. They were relieved when they reunited later that afternoon, and were happy to head home to see their children the next day.
Joe was on his way back from a business trip in Dallas on Wednesday when he noticed huge plumes of smoke as he passed through West. The next thing he saw was the massive fire ball from the explosion that shook his car as he was driving.
Dance teacher Adrianne Haslet-Davis was thrown from the blast at the Boston Marathon finish line. She realized immediately she needed to act to save her foot. After crawling to a bar for help, her husband, who was also injured, and a good samaritan tried to use their belts as tourniquets to stop the bleeding. Adrianne was relieved when they were finally taken to a hospital for care. When she awoke after surgery, she saw that her left foot and part of her leg had been amputated. In a moving interview, she's tells Anderson Cooper that she's determined to dance again and conquer the challenges that stand in her way.
