Narrative:

I failed to realize that the departure clearance was not requested, nor received, during the before start checklist. It was at liftoff that the first officer advised me he had failed to request the clearance. The clearance was retrieved via ACARS. I should have checked twice during the checklist and caught the missing clearance. Supplemental information from acn 409500: got distraction and forgot to obtain clearance via ACARS. Missed transponder item on checklist.
