A regional airliner crashed in a northeastern city in Brazil on Wednesday, killing all 16 people on board, the nation's Air Force said. The crew of the twin-turboprop aircraft belonging to Noar Airlines reported problems shortly after taking off from the city of Recife en route to the city of Natal. Investigators said the plane's flight data and voice recorders were located, which they hoped would help answer why the plane went down. Witnesses said at least one of the passengers was pleading for help after the plane made a hard landing, gesturing through a window to onlookers, but the aircraft burst into flames before aid could arrive. Amateur video obtained by local television station SBT, showed the plane on the ground in flames.
