SCP #: SCP-xxxx
Object Class: Safe
Special Containment Procedures: SCP-xxxx is to be left inside of a vault in Site-19. It is NOT to be worn inside of any building with more than 5 floors under any circumstances, but may be tested.
Description: SCP-xxxx is an indestructible black T-shirt with a picture of the twin towers in front of a dark starry night on it, and according to it's tag, is size S. Similar to SCP-714, the T-shirt expands and contracts to the most comfortable size, just before being put on. If the T-shirt is worn inside of a building with at least 6 floors, any floor under the top floor and above the halfway mark will start to burn next to any and all exits. This is accomplished through varying methods, whether through a gas/oil leak, or, in the case of 9/11, by a plane crashing into the building. While wearing the shirt, the wearer becomes immune to all bodily harm.
Further notes: SCP-xxxx was worn by Soren Peterson, 32, during 9/11. He was a senior software engineer in the Twin Towers and after he was evacuated from his building after the first plane crashed, was told he could enter the other tower to finish his work. After the second tower fell, the fire department found him lying underneath an estimated 4 tonnes of rubble. Because of this, he was questioned by the Foundation and after finding no useful infomation, he was given class C amnestics and put back into his home. 2 weeks after being released from the Foundation, he was found, once again, completely unharmed underneath an estimated 1 tonne of rubble after a fire started in his workplace. Once again he was questioned by the Foundation, and Dr. ███████ noticed that all of his clothes had changed from his last visit, except from his T-shirt, SCP-xxxx.
