ascend. Unlike the rest of his coworkers who went up the stairs, however, DiFrancesco reversed course and survived. Clark made his way to find Fuji Bank employee Stanley Praimnath, who was pinned underneath some debris behind a wall that had stood firm. Praimnath had initially evacuated the building after the first plane had hit the North Tower but went back inside as South Tower security gave clearance to reenter the building. Once he had arrived back at his office on the 81st floor, he was on the phone when he noticed the second plane coming right at him. He screamed and jumped under his desk as the plane was hitting the building. After the impact, Praimnath found himself alive under his desk with only minor injuries. When Clark found Praimnath, there was a wall standing between the two, and the only way for Praimnath to escape was to jump up and go over the wall. Praimnath was unsure he would be able to get over the wall but tried due to Clark's urging. Praimnath made several unsuccessful attempts to climb the wall, on one occasion injuring his hand, but he persisted, and on another attempt Clark was able to hook his arms around Praimnath and help pull him to the other side. Descent Clark and Praimnath's descent through the floors of the impact was impeded by some debris and smoke, but by moving the debris, they made it passable. The phones were working in Oppenheimer's offices on the 31st floor. Clark was on the telephone for over three minutes and talked to three different people before his 911 call was understood. This call might have been the only chance for rescue workers to learn that there was a clear stairwell that the several hundred people trapped above the impact could try to use to escape. Clark described how he and Praimnath did not feel a sense of urgency, and before calling 911 they each made one brief personal call. At 9:55 am, they got to the ground floor where there were rescue workers. One advised them to run once they exited onto Liberty Street, at the southeast corner of the complex. At 9:56 am, Clark and Praimnath ran out of the World Trade Center complex. Clark described how, when they had gotten about two blocks away, Praimnath told him he thought the buildings were going to go down. Clark was
