The National Transportation Safety Board (NTSB) has recovered both black boxes from the Air Canada Express CRJ-900 crash that killed two pilots and left dozens injured. The NTSB, the Port Authority and first responders cut a hole in the roof of the plane to access the devices, which were not damaged. The crash occurred at New York's LaGuardia Airport and was the first deadly accident at the airport in over 30 years. Two Port Authority police officers, Sergeant Michael Orsillo and Officer Adrian Baez, were among the injured, with 32 treated and released. The runway where the crash occurred remains closed as agencies continue their investigations.
