Officials say a British Airways flight from London to Houston has made an emergency landing at Chicago’s largest airport.

Chicago Aviation Department spokesman Gregg Cunningham says Flight 195 landed Sunday at O’Hare International after the pilot reported a problem on board.

British Airways spokesman John Lampl (LAM’-pull) says the crew detected an "electrical burning smell" and diverted the plane as a precaution.

Lampl says none of the nearly 90 passengers and 15 crew members were in danger. Engineers are evaluating the plane.
