No, the aircraft engine is not for Mighty plane and neither for a UFO.
For so far that engine is just an useless manufacturing item, good for nothing.

The manufacture of Mighty Plane is correct and you can check here:

But the manufacture of UFO seems strange to me, especially "Poop", but I ll get a design for UFO, or I ll ask my friend who has a UFO and UFO design.
