Can't see Mesh Collider in Unity5

I’m new at Unity and I’m following the tutorial that was designated for earlier versions than 5.
I applied a Mesh collider to my spaceship but after disabling the mesh render I still cant see the collider wires.
It isn’t minimized in the inspector if that’s an issue.
Am I doing something wrong here or is it just something that changed with Unity5 and I have to just deal with not seeing the mesh collider?

There are some limitations when using the Mesh Collider. Non-convex Mesh Colliders are only supported on GameObjects without a rigidbody. If you want to use a Mesh Collider on a rigidbody, it needs to be marked as Convex.

This. The tutorial was created for unity 4, apparently it was not like this then.
If you delete rigidbody, you instantly can see green lines of non-convex collider.

@bromi removing rigidbody doesn’t make non-convex collider visible. My current Unity version is 5.2.3f1. I solved visibility problem by marking collider as convex, and didn’t remove rigidbody.
