AF 447 Flight Recorder Found In the Atlantic

romiz writes "The memory of the flight recorder for the Air France 447 flight from Rio de Janeiro to Paris, crashed on June 1st 2009, has been found on the seabed of the Atlantic Ocean, and brought back to the surface in good shape. This is the data recorder, which saves the flight parameters. The search is still continuing in hope of finding the voice recorder containing the sounds recorded in the plane's cockpit."

Common law evolved with rules to accomplish the same thing, but the idea of innocent until proven guilty doesn't in itself prevent it. A long time ago the state could come and throw you in jail while it did its investigations, even if that took a long time. That is why laws were developed so that the state generally can't hold you more than a set period of time (24, 58, 72 hours or whatever, depending on the state) before having to release you or are charged and started through the court system (which I think ends up being similar to Napoleonic law, n'est-ce pas? :).

  51. Voice data for all flights by Satellite by Tisha_AH · · Score: 1

    There is more than one microphone on any voice recorder. There may be as many as five on some aircraft. Also, degrading the sound quality by lowering the data rate can mask other sounds that are even more critical than a flight crews last words.

  52. Just leave the car open with key in ignition by Anonymous Coward · · Score: 0

    Gee, it would be cheaper simply to not lock the car and simply buy a new one when it gets stolen.

    Yes, I know that auto theft is a serious crime, but I don't get this business of conducting a high-speed chase to nab some loser who has stolen a car.

    Like I was watching this episode of "Cops" (you betcha I watch it, it shows the whole 'tude of law enforcement), and they are chasing this guy. In a 10-year-old Saturn. I mean they are endangering the public to get this guy who stole a clapped-out GM car.

  53. Several reasons: by sirwired · · Score: 1

    1) This would help in surprisingly few crashes. Most crashes take place during "normal" takeoffs and landings.
    2) Over the ocean, you'd need a parachute AND a life raft. (A dinky little inflatable life jacket isn't going to cut the mustard on the open ocean where hundreds of your fellow passengers are spread over miles and miles of (likely rough) water with NO floating aircraft bits to hold on to. And that's if you survive to get in the raft. Good luck having more than a few untrained people successfully ditch the parachute, swim to the surface, and find their life raft (while fully clothed) before they drown.
    3) Over land, there is usually plenty of time to glide to an alternate airport (or smooth patch of ground.) If you have land smooth (and soft) enough to land untrained people in a parachute, it should be good enough to land the plane.
    4) If the plane starts to break up, stall due to icing, etc., it would be in no condition to evacuate via parachute, as it almost certainly is not in smooth controlled flight at the time.
    5) The plane is going too fast.
    6) You can only evac through exits where your tumbling body isn't going to hit anything like the wing or tail.
    7) You can't start the evac until the plane hits 10,000 ft or so. Before that the doors can't even open because of the pressure difference, and even if they could, you'd pass out due to hypoxia. (Bad Hollywood movies notwithstanding.)
    8) Parachutes are HEAVY. You'd chop the passenger capacity of the aircraft by quite a bit by supplying everybody with a parachute.
