Airplanes are great projects

Every time you fly, you can't help but see the plane from an engineering perspective。

From the perspective of engineering design, it gives birth to large-scale engineering software like CATIA, how many engineering talents it has achieved, and how many precision manufacturing it has promoted。

The natural flow of the wings, the powerful turbine engines, and the way they connect to the fuselage, it's the pinnacle of engineering, it's impressive。
