After the WTC towers collapsed it was reported that 20 people were pulled out alive from the rubble. Some of the most famous cases include police officers John McLoughlin and William Jimeno, who were on the main concourse between the two towers when the South Tower collapsed. They were saved after entering a freight elevator, but almost died from their injuries. Another incredible story is that of Genelle Guzman, who survived a fall from the 13th story of the South Tower. She was knocked unconscious during the initial crash and woke up alive in the rubble. Guzman was the last person found alive. She was discovered by a German Shepherd named Trakr 26 hours after the collapse.This video shows the initial response to 9/11 after the towers had been struck by the aircraft. The impact caused significant damage to the streets below the buildings, which can be seen in the footage. You can also see people hanging off the towers. In one case, the tape captures a man falling to the ground. The footage is horrifying, but shows a common event that occurred on 9/11.The video also shows a minor explosion in the tower which causes a large object to shoot out from the building. The cameraman responds by saying “did you see that blowout.” This section of the video has been reposted many times under the title of WTC exploding man, with the suggestion that the clip shows a man being blown from the tower. The video finishes with some shots of firefighters entering the buildings. Sadly, many of these workers were killed in the terrorist attacks
