USS Olympia

"Harry Burkhardt isn't sure what it was. He just knows he encountered "something strange" last month in the boiler room of the USS Olympia. "I felt two hands grab my arms - and they were icy cold," said the longtime ship volunteer, who described turning around and finding no one there. The same month, a couple of visitors told Chris Hall, a visitor-services worker, that they saw the translucent form of a man appear. And in July, visitor Melissa Miller said she saw a "full-body apparition manifest" in the engine room, then vanish. The unusual happenings aboard the Olympia - last surviving warship from the Spanish-American War of 1898 - have drawn the attention of paranormal investigators, including SyFy's Ghost Hunters, which came to the Penn's Landing attraction this month to check out the reports."
