The biggest airshow in China 202 1 kicked off in Zhuhai on September 28, 2021 and drew a close on October 3, 2021, showing the world's top new ideas and new ways. The Z 20 helicopter (直升飞机) caught people's eyes.
Helicopters can do many things that airplanes cannot do. Unlike an airplane, a helicopter can fly to one place more easily. They can take off without a runway and they can land where there is not enough room for an airplane to land. Some small helicopters can carry just one person. Larger helicopters can carry many people and heavy things. They can also help carry food or something else to remote places while other vehicles (交通工具) are difficult to reach.
Firefighters sometimes use helicopters to help fight wildfires. They drop water on the fire from the helicopters and the fire is put out successfully. Police also use helicopters. Police helicopters have strong lights. They can shine down on the ground to help police find things more easily. Doctors also use helicopters to bring sick people from one place to another quickly.
There are more and more helicopter pilot schools in our country. Helicopters will play an important part in our life in the future.
