Why does Wuxi plane close the window?

The air pressure is low, repair the window.

The higher the plane flies, the lower the air pressure will be. Opening the window will make it difficult to breathe, which will cause the plane to lose its balance. It is very dangerous to use fixed windows when making airplanes, so Wuxi airplanes have to close the windows.

There is Sunan Shuofang International Airport on the plane of Wuxi, which is called Wuxi Shuofang International Airport by the civil aviation system, with a linear distance of 10.8km from the center of Wuxi. This is a 4E-class international airport for military and civilian use.
