Montauk Long Island has a history shrouded in secrecy. This is where the government operated a lab to experiment with theories opened up by the original Philadelphia Experiment. Among other things, the government Scientists were in Montauk tinkering with time travel, extra-dimensional exploration and teleportation.
It should also be noted that after the Montauk Base closed down and its system of underground tunnels filled with concrete, the government opened an "Animal Testing" lab a few miles away. Is it possible that this lab is merely an outgrowth of the research done at Montauk?
Time to call Captain Jack and Torchwood!
