Our brain and senses are made out of fundamental particles too, and the image of a plane with wings is the result of the interaction between the fundamental particles out there with the fundamental particles in us.
So I would I say the plane image is an effect not a primary, but that does not make it any less real than the primary. It is a real thing, just as real, that just happens to be further down the chain of cause and effect.
