So why is the media saying that a French Nuclear Submarine is going to look for the Black Box on Wednesday ?
Somebody has got to get their story straight.
Was the plane brought down in some JFK style plot to get rid of these HIGH PROFILE CRIME FIGHTERS look here...

Personally, I don't see the benefit of going through every conspiracy theory that comes down the pike but I have no doubts you can find an audience.
A passenger on board of a TAM Linhas Aereas Airbus A330-200
registration PT-MVH performing flight JJ-8098 from Sao Paulo Guarulhos (Brazil) to Paris Charles de Gaulle (France)
bound to land in Paris about 40 minutes past AF-447
, reported that they were about 4 hours into their flight, when the airplane experienced severe turbulence and began to violently shake. The pilots performed an emergency descent to get into calmer air. Only after about 30 minutes the turbulence ended. Subsequently the airplane reached Paris without further incident.
Specifics on Airbus pitot tube issue:
Two incidents of note preceding AF-447:(1)
An Air France Airbus A340-300, registration F-GLZL performing flight AF-279 from Tokyo Narita (Japan) to Paris Charles de Gaulle (France), was enroute at FL310, when the airplane went through a line of thunderstorms. The captain's air speed indication suddenly dropped to 140 knots, the systems issued an alert regarding disagreeing speeds (NAV IAS DISCREPANCY), the navigation display showed a tail wind component of 250 knots. The captain released control of the airplane to the first officer and tried to switch his display from ADIRU1 to ADIRU3. 2 minutes later autopilot and autothrust disconnected and the fly by wire changed into alternate law. The crew noticed icing conditions (static air temperature [SAT] -29 degrees Centigrade) and switched anti ice including pitot heating systems from automatic to on. The speed indications became normal again and agreed again, the autoflight systems were reengaged and ATC informed of severe icing. ATC reported, that two flights had just passed the location without problems. When the crew attempted to reset and reengage ADIRU 1 two times, the system again brought the message "NAV IAS DISCREPANCY" on both attempts, although the speed data appeared consistent. The crew suspected polluted pitot tubes.
Maintenance found, that the drainage holes of all three pitot tubes had been clogged, rendering it very likely that weather combined with the clogged drainage holes caused the incident. Maintenance had reported more clogged drainage holes on A330 and A340 aircraft in the past to Airbus Industries. Airbus Industries was aware of the problems, changes had already been introduced to the pitot tubes on the A320 family, where similiar problems had occured. A modification of the A330/A340 pitot tubes was already planned by AI.(2)
An Air France Airbus A340-300, registration F-GLZN performing a flight from Paris Charles de Gaulle (France) to New York JFK,NY (USA), encountered brief turbulence while enroute. The autoflight systems dropped offline, "NAV IAS DISCREPANCY", "NAV PRED W/S DET FAULT" and stall alerts were repeatedly issued during the following two minutes. The airplane continued to JFK without further incident. A review of the policy of retrofitting pitot tubes was recommended and authorities informed.
Air France said, that Airbus Industries had issued a recommendation to retrofit the pitot tubes in September 2007, giving the operators full freedom to decide about the implementation of the recommendation. Air France had implemented the recommendation to their A320 fleet, but did not retrofit the long range A330s and A340s due to the absence of incidents. Starting May 2008 Air France however observed the loss of air data on their A330 and A340 fleet. These incidents were discussed with Airbus Industries, who identified the problems as icing related and suggested that the modification implemented on the A320 would not resolve the icing issue. In the first quarter of 2009 laboratory tests however proved, that the new pitot tube design establishes a significant improvement over the previous design. Following a test flight Air France began to implement the retrofit of the new design pitot tubes onto their A330 and A340 fleet on April 27th 2009. Without prejudice Air France has now decided to accelerate that program to retrofit the pitot tubes on the A330/A340 fleet.
