Seems that they computer systems automagically picked up on calls being made very closely spaced in time from many different cities and that they did not fit out 'usage pattern'. They specifically wanted the access code left live until they could try to track down the callers who were using it. All in all, they did a good job of keeping the customer happy and well informed, and impressed me with the capabilities of their software to extract features that indicate abuse. I would appreciate any evidence to elaborate. After the negative terminal is disconnected the positive terminal may be brought into contact with the frame without ill effects.

There were several Japanese simulations of the attack on Midway. The first simulation took into account the Japanese forces, the American forces, relative skill levels, and the like. The simulation was played, and the result of the simulation was that the Japanese lost. This was unacceptable to the admirals, since they knew that they had a superiority in force strength, better intelligence, and the advantage of surprise, so they ordered the rules of the game to be redesigned. After a couple of iterations, playing the simulation produced a Japanese victory in line with what the admirals expected from their plans.
