Thousands of persons in Peru are suffering from the disease cholera. Medical experts say it is the first time in their century that cholera has reached the western part of the world. The United States Centers for disease control says the kind of cholera has been spreading throughout the world since 1961. It was discovered that year in Indonesia. Since the first case in Peru, more than sixteen thousand people have been affected and about one hundred have died.

Today, air travel is far safer than driving a car on a busy motor-way. But still there is a danger that grows every year. Airliners get larger and larger. Some airplanes can carry over 300 passengers. And the air itself becomes more and more crowded. If one large airliner struck into another in midair, 600 lives could be lost.

From the moment an airliner takes off to the moment it lands, every movement is watched on radar screens. Air traffic controllers tell the pilot exactly when to turn, when to climb, and when to come down.

The air traffic controllers around a busy airport like London-Heathrow may deal with 2,500 planes a day. Not all of them actually land at the airport. Any plane that flies near the airport comes under the orders of the controllers there. Even a small mistake on their part could cause a terrible accident.

Recently such a disaster almost happened. Two large jets were flying towards the airport. One was carrying 69 passengers from Toronto, the other 176 passengers from Chicago. An air traffic controller noticed on his radar screen that the two planes were too close to each other. He ordered one to turn to the right and to climb. But he made a mistake. He ordered the wrong plane to do this. So, instead of turning away from the second plane, the first plane turned towards it. Fifteen seconds later it flew directly in front of the second plane. They avoided(避免) each other by the smallest part of a second. The distance between them was less than that of a large swimming pool. This is an example of the danger that grows every year.
