SERENA, IL (WHBL) - A Sheboygan escape artist pulled off one of his most daring stunts on Tuesday. Anthony Martin shackled himself in a locked casket and fell out of a plane 14-thousand feet in the air. The stunt took place at a farm near Serena Illinois, about 70 miles southwest of Chicago. Martin was dropping at up to 130-miles-an-hour while he picked the locks of his shackles, and then struggled to open the door of his casket just in time to parachute to the ground. He somersaulted out of the casket. When he hit the ground, the 47-year-old Martin waved to the cameras and the crowd that looked on. The only injury was to a skydiver who scraped an arm and cut his lip, while trying to make the box steady before it was pushed out. Martin started teaching himself to pick locks when he was six years old. He’s been an escape artist ever since – and he pulled off yesterday’s jump one other time - in 1988. Martin chronicled numerous experiences in a recent book called “Escape or Die.”
