The head scientist is a chap called professor Jennings he explains that this site is a relic from the British attempts to recreate the American Philadelphia Experiment, inadvertently greating some sort of temporal vortex. The scientists are confident that they can send the PCs back to the right time but they are having difficult focusing the other end of the temporal vortex.
The entry point for the vortex is below the main gantry of the central tower the PCs dropping through into it. They black-out as soon as they jump into the vortex, when they come to they are falling through the roof of a barn into a haystack.
The barn is approximately 1 mile from the site of the Nazi research facility in the foothills of the Bavarian mountains.
