Of course you don't need an engineer to build (most) simple houses - at least our present contractor and most in general do very fine without one, and all of which I know have absolutely zero post-secondary education under their belt.
As mentioned before, civil engineers are brought in to work...

As for you aviator, I would probably recommend that you humble yourself and try to actually learn some actual physics.
