There is an old Chinese saying: Disasters fall from the sky. How true it is. The lightning conductor on top of the UMNO building fell down from the " sky" and killed an innocent passer-by. According to a report, the force is equivalent to that produced by 70 buses full loaded with passengers. For your information, the lightning conductor increases its speed by 9.81 m/s each second as it falls. The thrust it produces is given by Newton`s second law. Due to the large mass and height, you can imagine how much force it produces when it hits an object. The large amount of force can drive an object many metres into the Earth.
