A Seattle-bound jetliner aircraft has made an emergency landing in Portland, Oregon in the United States after the pilot lost consciousness.
Alaska Airlines spokesman Paul McElroy said the co-pilot landed Flight 473 safely after declaring an emergency to get priority care for the pilot.
The spokesman says the pilot lost consciousness "somewhere over Oregon". He later regained consciousness and left the cockpit.
Mr McElroy says a doctor on board tended to him in the cabin. The pilot has been taken to a hospital but there was no immediate word on his condition.
Mr McElroy said the pilot has been flying for Alaska for 28 years and was current on his six-month medical evaluation.
