A Southwest Airlines Boeing 737-300, registration N387SW performing flight WN2294 from Nashville,TN to Baltimore,MD (USA) with 126 passengers and 5 crew, was climbing out of Nashville through FL340 about 24 minutes into the flight, when a hole of about 30cm by 30cm (1 foot by 1 foot) opened in the cabine ceiling just before the root of the vertical tail. The cabin pressure was suddenly lost, oxygen masks deployed and the crew initiated an emergency descent reaching 11000 feet 6 minutes later. The crew decided to divert to Charleston's Yeager Airport,WV , where the airplane landed safely 20 minutes later. No injuries occured.
A replacement Boeing 737-700 registration N715SW resumed the flight and reached Baltimore with a delay of 3.5 hours.
The FAA and NTSB are investigating.
