» That’s what the black box recorders say: Details are finally coming to light about Air France Flight 447, which crashed mysteriously two years ago. While officials found debris from the flight weeks after the crash, the flight recorders weren’t found until recently. According to the recently-discovered black box, the plane descended at a speed of 180 feet per second. Evidence shows that the least-experienced of the pilots led the flight until nearly two minutes before the crash. Officials recovered the two flight recorders 12,800 feet beneath the Atlantic.
