As the plane lands, the piston forces the oil through the hole.

This compressed air which absorbs the impact of the land like the spring, once the plane landed

the compressed air expanded forcing the piston backup. This forces the oil back through the

hole which slows the piston movement prevents it from rebounding quickly.

By adding the second fuselage on the top of the first creating the rigid backbone for the entire
airplane.

 

Most of convey airplanes have the same structure.
