They blew up three cars. Each using different explosives and different methods so that the people could learn to respond to a bombing. So they described the scenario of a bomb inside a car as not being consistent with the victim of a car bombing, but being consistent with somebody transporting a bomb. And then they blew up these cars. So even after they've taught people that this is a very rare scenario, for a bomb to be inside a car, two of the three cars that they blew up at bomb school in 1990 had the bombs inside the car.
Nobody remembers where.
I said the bomb contained both a motion device and a timing device. The timing device consisted of a stop watch with the minute hand broken off, and a screw drilled in the clock face that was attached to a wire, so that the hour hand had to tick down until it touched the screw. Now this was not an accidental explosion. It was a wind-up pocket watch, so it had to have been set, consciously wound, and expire. I believe that the screw was in the nine.
