Narrative:

We inadvertently landed without a landing clearance. We were both fatigued and busy in bad WX. Approach never handed us off to tower, and we failed to follow up. Both our 'backup memory aids' for landing checklists failed, on the same approach. Incredible! I'll just be even more careful in future.
