Football-sized hole forces jetliner's emergency landing

(CNN) - A Southwest Airlines jet made an emergency landing in Charleston, West Virginia, on Monday after a football-sized hole in its fuselage caused the cabin to depressurize, an airline spokeswoman said.

There were no injuries aboard the Boeing 737, which was traveling at about 34,000 feet when the problem occurred, Southwest spokeswoman Marilee McInnis told CNN. The sudden drop in cabin pressure caused the jet's oxygen masks to deploy.

Southwest Flight 2294 was en route from Nashville, Tennessee, to Baltimore, Maryland, with 126 passengers and a crew of five aboard, McInnis said. What caused the damage to the jet had not been determined, she said.
