The document provides an account of the alleged Philadelphia Experiment conducted by the U.S. Navy during World War II. The goal of the experiment was to make naval ships invisible to radar using intense electromagnetic fields. According to legend, the experiment on the U.S.S. Eldridge not only made the ship invisible to radar but caused it to briefly disappear and teleport to Norfolk, Virginia before returning to Philadelphia. While the U.S. Navy denies the experiment occurred, some details are consistent with known Navy research at the time into using electric and magnetic fields for camouflage or "cloaking" ships.
