Narrative:

Advised to contact tower for visual landing clearance at the FAF. Perfect flying conditions and all radios were tuned accordingly. It was a textbook stabilized approach with zero distractions. I as the pilot monitoring simply failed to obtain a landing clearance for no reason at all. We were both completely baffled at the oversight. I have zero excuses to why this happened.
