Air France Flight 447 crashed into the Atlantic Ocean in 2009, killing all 228 people onboard. Although some major wreckage was removed from the sea within five days of the crash, it took another two years and €32m for the black boxes to be recovered from the ocean floor.
"There's a tombstone mentality at times. You actually have to have a very tragic event to get things done. I predict that this is one of those events," said Bob Benzon, a former US Air Force pilot and NTSB investigator. He said it would cost billions of dollars to fit out every single plane in the world with flight data real-time streaming capabilities.
