A Southwest Airlines Boeing 737 was climbing out of LaGuardia Airport, passing through 32,000 feet, when the left engine sustained an uncontained failure, subsequently causing debris to be ejected and impact the air frame. A passenger window was shattered as a result of the debris impact which then caused the cabin to depressurize. This prompted the flight crew to initiate an emergency descent and divert to Philadelphia International Airport where the aircraft performed a safe landing. A passenger sustained fatal injuries as a result of the debris impacting their window. A post flight inspection found that the aircraft sustained substantial damage.
