The saying "What goes up must come down" is an appropriate starting point. If you fire a gun into the air, the bullet will travel up to a mile high (depending on the angle of the shot and the power of the gun). Once it reaches its apogee, the bullet will fall. Air resistance limits its speed, but bullets are designed to be fairly aerodynamic, so the speed is still quite lethal if the bullet happens to hit someone. In rural areas, the chance of hitting someone is remote because the number of people is low. In crowded cities, however, the probability rises dramatically, and people get killed quite often by stray bullets. Most major cities have laws in place to try to keep people from shooting guns into the air in celebration.
Spies can have fake wives, fake degrees, fake interests and fake lives. Spies are often romanticized in Hollywood, but how does James Bond compare with real spies? And what happens when a spy is spying on the people he's supposedly spying for?
At the Carnegie Mellon debut, a Crusher prototype rolled over and crushed piles of cars that would have most monster trucks backing up with their tails between their legs. Crusher is no typical truck. It can drive right over a 4-foot vertical wall while carrying 8,000 pounds of cargo – and no people.
