Is there ANY possible way to use a mesh collider(without convex) with a rigidbody?

I am creating a game with airplanes involved. It is extremely important that i get the collider to fit exactly to the airplane. I am also using a rigidbody with the airplane, so unless I check Convex the airplane will not collide properly. Is there any asset, scripting, or any method at all that will allow this to work? I don’t need work done for me, I just want guidance. Thank you:)

You can use multiple colliders as children, preferably primitive colliders, but if that’s not possible then use multiple convex mesh colliders. Every possible shape can be represented that way.
