AET is called in to investigate an extra subway.
One hears strange stories from time to time about the things that go on under a city. Are there really alligators in the sewers ?
The engineer who reported the extra subway tunnel was quite nervous. He had seen too much. He knew enough to recognize potentially what he was looking at, and it was mind-boggling. A subway was under construction in a growing city and the construction acted as a cover for something else. First the police got contacted, then the army, and the AET. AET investigated the extra subway tunnel revealing some interesting findings.
The tunnel was inclined at an angle of about 15 degrees. The tunnel was almost cylindrical, deviating from a cylinder shape only to allow for two rails to support some sort of vehicle. It ran in a straight line along an east-west axis. The tunnel ended at a hillside about a kilo-meter outside of the city. The entrance was hidden by some shrubbery and a tarp, and was located on fenced-in private property. An additional concern was what was found inside the tunnel.
At the lower end of the subway tunnel were a number of "subway" cars linked together. The cars appeared to made out of an extremely strong lightweight aluminium alloy. The cars were almost cylindrical in shape. The lead car had a bullet-nose shape to it. They were all streamlined for high-speed. There was a cowling around the lead edge of the cars that formed a seal with the tunnel. Inside the lead subway car there were a set of what appeared to be aeronautical flight controls. A strange set of controls for what was supposed to be a subway train. The trailing car was what appeared to be some sort of a rocket engine. When looked at as a whole it was obviously not a subway, it was an orbital launch platform. The "subway" ran along an east-west axis in order to use the rotation of the earth to provide additional boost.
A small amount of uranium based nuclear fuel was found at the site. The launch platform appeared to be about 90% complete and was apparently abandoned for some reason. Perhaps they had too much trouble getting fuel for the project.
AET specialists dismantled and warehoused some of the stranger equipment, leaving behind only what appeared to be a non-standard subway train. The train was salvaged by the army, and the empty cars sold as scrap aluminum. Then the entire subway tunnel was filled with cement to ensure an end to that project.
