A UPS United Parcel Service Boeing 747-8 freighter, registration N624UP performing flight 5X-110 from Anchorage,AK (USA) to Tokyo Narita (Japan), was enroute at FL380 over the Bering Sea about 670nm westsouthwest of Anchorage when the crew decided to return to Anchorage reporting fumes/hazmat exposure on board. On approach to Anchorage the crew advised they needed medical services to meet the aircraft at the apron. The aircraft landed safely on runway 15 about 3:10 hours after departure. The crew was taken to a hospital.

Emergency services reported they responded to a 747 that turned back after the crew experienced symptoms associated with hazardeous materials. Hazmat teams were checking the aircraft. The aircraft was pressurized later the day to ensure that no hazmat was present.

The aircraft is still on the ground in Anchorage with all doors open to ventilate the airframe.
