UPDATE: The Associated Press reports that the man has died.
EARLIER STORY: A flight headed from Houston to Seattle made an emergency landing about 8 p.m. Thursday at Boise Airport when the crew reported that someone on board had suffered a heart attack, Boise airport spokeswoman Patti Miller said.
A United Airlines spokeswoman told the Associated Press that it was a member of the crew that suffered a medical emergency, contrary to initial reports that it was the captain.
Miller said the 737 landed safely within about five minutes of the United Airlines 1603 crew reporting the need for an emergency landing.
Miller did not have an update on the condition of the person, but said he had been taken to a local hospital.
There were about 160 passengers and five crew members on the plane, she said, who were waiting at the airport until another pilot could be found or other arrangements could be made to get the group to Seattle.
