Around October 28, 1943 the U.S. Navy destroyer escort USS Eldridge (DE-173) was getting prepared for an experiment

This was an experiment by the  U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania. They wanted to try to make the ship invisible or cloaked for enemy radar and other detection devices.

The ship disappeared. And was teleported in another time (and space). 

Bermuda Connection?

The Bermuda Triangle is a notorious place to be, or not to be?
Throughout the years there have been reports of sudden disconnections of radar and radio communications and mysterious disappearances of ships and airplanes. The link with the Philadelphia Experiment is; water, which is mysterious by itself. Having different forms like; liquid, steam and solid, when it's frozen. Water is an important element.

Theories & Secret Technologies?

What the cause may be regarding the Bermuda Triangle disappearances is still unclear. There are various theories, from deep undersea streams, methane gas to star gates and even UFO's.

Things may see the world and the world may see things when the Arctic ice is melting. Uncovering what has been hidden in the ice for centuries.

Ice is frozen water.

In the 1930's Nikola Tesla got involved with a group with was experimenting with moving through the Time/Space continuum. In the early 1930's, the University of Chicago investigated the possibility of invisibility through the use of electricity.

In 1939 this project was moved to Princeton's Institute of Advanced Studies, this is not far from Philadelphia. There they were able to make small objects invisible. They presented this technology to the government. The military, because we were at war wanted to pursue it in their direction.

Tesla had come to the same conclusion that Einstein did that this technology if developed would not be used for the benefit of mankind.

In 1943 the government conducted a test using domestic animals on a ship. The ship that was eventually used for the experiment, the USS Eldridge, was commissioned at the New York Navy Yard on August 27, 1943 (Department of the Navy). The animals were placed in metal cages on the USS Eldridge. The ship became invisible but when it materialized many of the animals were missing on had radiation and other burn marks on them. Humans were not to be tested.

Yet on August 12, 1943 the USS Eldridge with a full crew aboard reportedly underwent the Philadelphia Experiment. The men did not know what was to happen. The generators were fired up. The switches were thrown. The ship disappeared and all seemed well.

However, others claim that the experiment took place on October 28, 1943. Substantial evidence points to the October date as being more accurate. The Navy has released the Eldridge's deck log and war diary and at no time was the Eldridge in Philadelphia. However, the records could have easily been changed.

The Eldridge's war diary reads as such: The Eldridge remained in New York and the Long Island Sound until September 16, when it left for Bermuda.
