Narrative:

Detroit approach never told us to switch to detroit tower on ILS runway 3R. We did not notice and landed in dtw without landing clearance. After landing, we switched to tower to report clear of runway. They just told us to contact ground. It was early in the morning and we only had about 6 hours sleep and just didn't pay attention.
