Performed under the guidance of professor Albert Einstein, the Philadelphia Experiment was the first successful application of the chronoshift technology. However, as Prof. Einstein remarked, during the experiment they had very little control over the effect, and gaining that control was the entire objective of the Chronosphere project.
The experiment consisted of two relay towers positioned on the sides of an Allied cruiser, which generated a chronoshift bubble, making the ship disappear and reappear a few moments later. However, due to the nature of the effect, the navy corpsmen who were on board as part of the experiment, suffered horrible fates, as mentioned by Einstein. Witness accounts mention people that were outside when the effect was deployed were fused with parts of the ship or horribly mutilated.
Further information on the Philadelphia Experiment was classified by the Allied Forces.
