CHICAGO (AP) — An American Airlines Boeing 757 blew a tire and ran off a runway Monday during an emergency landing at O'Hare International Airport, aviation officials said.

No injuries were reported, the Federal Aviation Administration and the airline said. The plane came to rest with its wheels on a grassy area off the runway.

Flight 268 was en route from Seattle-Tacoma International Airport to New York's Kennedy International Airport when a cockpit indicator light alerted pilots to an "electrical system issue," said American spokeswoman Mary Frances Fagan.

The plane was diverted to O'Hare and landed at 1:42 p.m., blowing a tire after it touched down.

In other incidents Monday, a passenger jet carrying more than 60 people ran off an airstrip in Ecuador's capital of Quito, skidding some 400 yards and smashing through a brick wall. None of the 62 passengers or the crew members aboard the Fokker F-28 were injured.

In Atlanta, a Northwest Airlines flight traveling from Orlando to Detroit was diverted after a warning light indicated a mechanical problem. Flight 423 landed without incident.

And a United Express flight had to brake and swerve at 140 mph to avoid a small plane on the same Pennsylvania runway, airport and federal officials said Monday. The flight crew of Chicago-bound Flight 7138 spotted the Cessna four-seat propeller plane just ahead of it and aborted takeoff Friday night at Lehigh Valley International Airport, the National Transportation Safety Board said.
