France's BEA air accident investigation bureau confirmed that it has found one of two black boxes from the Germanwings A320 that crashed in the French Alps just before 11 a.m. local time today. The investigators have yet to confirm whether they have found the flight data recorder or the cockpit voice recorder.
A spokesman for France's DGAC civil aviation authority told AIN that no distress call or signal came from the aircraft. However, an air traffic controller triggered an emergency response at 10.30 am. local time after he observed that the A320 was descending and not responding to radio communications.
