Ask an Explainer
I was just on a plane and the engine was not under the wing,it was hanging off of the side! Is that normal?
In principle, it makes no difference where you put the engine. There is no difference in terms of thrust: it’s just a design preference.
Putting the engine on the side of the wing makes the plane closer to the ground, which means the landing gear can be shorter, saving the company some money on materials.
