    Just one more comment, thank you. If and when .41 cu feet is averaged against the sensors in a storm situation it could lead to the actual sensors themselves sustaining damage which is not repairable. So my idea is not to use the 41, or get some pitot tubes that can withstand that type of wind, or they will probably break again.

    Certain Vertical Stabilizers have had to be thickened because they were too thin, this one may qualify for that. It is Just that I notice that the 57.931 feet is just a lot of weight already if set there to really be running without a metal vertical stabilizer, or at least one that has been thickened. If the plane is averaging weight pushed down by the weight of the horizontal stabilizers as this one appears to be doing it may be too much and it may be forming a different form of control factor on the plane as the weight would increase with the distance of the horizontal decrease in distance. If this is so a motion would be created which could detract insignificant amounts of mass from the wing in the storm which however insignificant would add up to a difficult issue. This is because that when the planes wings are under by 1.01 feet an additional .3 cu. feet would have to be understood from the standpoint of setting the tail exactly the storm would probably take about .70 cu. feet away from the wingset leaving approximately .41 cu feet difference. This means that the stability of the plane would be compromised in a shifting motion. Most of the sensor data returns through this area and if blocked could lead to sensor malfunction under high wind rate.

    A330s are equiped with a SATPHONE system. I found a reference to this in an accident report which involved an A330 from last year. Voice communication from AF447 to Air France maintanance seems very likely. I am surprised that this isn't getting more attention given the urgency to find the voice recorder. A link to the accident report is provided.

    it does not look like the plane came down but vanished in thin air and sarkozy is least bothered to investigate it ,how can in the day when they monitor my telephone from space can a plane go missing without a trace is rather a very pathetic joke .

    Perhaps, there was no communication between the flight, and the air traffic control authorities involved. Perhaps, the communication was not working, between the air traffic control authorities, and the flight.The plane has a glide path, when it descends. The pilot had ample time to convey an emergency. How all the modes of communication did not work, is a wonder. The aircraft seems to have sunk, because no debris was found. I say, "seems".

    Various arguments have been presented as to why Air France 447 was lost at sea. These include structural breakup, computer failure, sabotage, electrical failure, and an electrical fire. What has not been put forth as a possible explanation is unstoppable blinding smoke in the cockpit. I???m not suggesting that smoke in the cockpit is the answer. I???m only advocating that it is a possibility, one not previously offered, and no less plausible an hypothesis than any other.

    On average, there is one unscheduled or emergency landing in North America daily. Most aircraft land without incident. But In July 2007, a NASCAR corporate twin-engine aircraft crashed. It experienced a short circuit. The wire insulation burned and that led to a cry of ???smoke in the cockpit.??? The aircraft crashed two minutes later. A short circuit lead to the fire and smoke in the crash of Swissair 111. It???s crash, like the crash of ValuJet 592 that preceded it, began with the cry ???smoke in the cockpit.??? These three examples and many others can be found in a 16-page report listing aircraft in which smoke was a cause or a factor in aircraft incidents and accidents. (See: http://www.smokeinthecockpit.com/references/List-of-Some-Smoke-Related-Accidents.pdf )

    Electrical failures can lead to blinding smoke in the cockpit. Contrary to a common perception, pilots cannot see when unstoppable blinding smoke enters the cockpit. Air France 447 signaled that it was loosing cabin pressure. When smoke invades the cockpit, the Federal Aviation Administration recommends that pilots depressurize the aircraft to force the smoke out. If the smoke were a one-time event, this procedure would likely work. However, when the smoke is continuous, depressurization cannot help. The pressure on the outside and inside of the cabin would be equalized. Continuous smoke would build up, blinding the pilots.

    Let me reiterate. I am not stating that continuous blinding smoke brought down Air France flight 447. I am saying that continuous unstoppable blinding smoke in the cockpit is an equally worthy hypothesis to consider. For those interested in more information on the subject, you might want to read Air Safety Week???s overview of the unsafe condition of smoke in the cockpit: http://www.smokeinthecockpit.com/references/Air-Safety-Week-Smoke.pdf

    You can also read a recent (May 21st) U.S. House of Representative amendment to the FAA Reauthorization Bill (http://www.smokeinthecockpit.com/references/GAO-Amendment.pdf) that requires the Government Accountability Office (GAO) to study the unsafe condition of unstoppable blinding smoke in the cockpit.

    The puzzling part... WHY would a pilot knowingly fly into a thunderstorm cloud while being in the knowledge that for more than one hour he would not have communication with ground control? This just defies all logic. Moreover wouldn't you expect the plane fly on such high altitude that the storm would be well below and not able to affect the its flight? If pilots are trained to fly around a thunderstorm why did this pilot apparently flew INTO it? Isn't that asking for trouble? Much like walking through fire and expecting not to get burned?
    Turbulence would be a reasonable explanation why a plane would end up in the middle of a thunderstorm. Then again, the oil slick indicates there was no explosion or fire unless the oil slick comes from another vessel. Lots of questions and very few answers.

      If the plane had trouble with it's electrical system then it's possible that they lost their weather radar and had no idea that they were flying into a storm. Since this ocurred at night they would literally be flying blind without that radar. As to the question of height, the plane was flying at roughly 36,000 ft. and some thunderstorms will reach 50,000 plus feet into the atmosphere. By the time they realized they were in a storm it would have been too late.
