Narrative:

Delaying vectors due to stage 3 noise restrs so as to land at XA00 or later. The crew was cleared for the approach and neglected to contact the tower to verify landing clearance. The flight did not acknowledge landing clearance. The crew contacted the tower after landing. Possible reasons: fatigue due to the captain being awake for 26 hours, first officer awake for 31 hours and flight engineer awake for 29 hours, due to the fact that they all commuted to work the day before, operated jfk-day-sea with a 4 hour delay in jfk leading to no rest in day before departure to sea.
