Excellent new article talking about 'sidestick' issues. Comments make for an interesting read, too. |

i disagree, now that they figured out what happend they are going to be taking steps to fix this which reduces the chances of it occuring again. |

It was human error |

Exactly. Therefore it's avoidable. |

'People look at the arrivals screen showing Air France flight AF447 as "delayed" at Charles de Gaulle airport near Paris June 1, 2009.'
bad stuff.. |
i have a Degree in Aerospace Engineering.
in 2nd year, 1st semester, in a class called Fluid Mechanics the Professor (he has worked for NASA) tried to shed some light on how an airplane actually flies.
(AKA, the aerodynamic theory of what makes an airplane actually fly)
and to the silence of the whole room, he proceeded to tell us, that to this day, no one has yet figured out how a plane actually flies.
Airplanes fly, but no one has yet to provide the actual theory behind how airplanes, or why airplanes actually fly. |

From the analysis they've been able to conduct already, they believe that nozzles, used to direct air-flow to a device that measures air-speed, froze solid when the plane entered a massive storm bank. Unable to determine how fast they were going, pilot confusion led to a series of errors that resulted in the plane stalling. There are actually procedures for avoiding the stall in such conditions but the pilots may not have ascertained the severity of the problem in time to fix it. It should be interesting to find out if that is the case or what it actually was. |
first rule of flying:
if ice forms anywhere on the plane, that plane needs to land...or passengers = death.
" they believe that nozzles, used to direct air-flow to a device that measures air-speed, froze solid when the plane entered a massive storm bank"
those nozzles that take in air-flow input are either on the engines or on the wing.
ice anywhere on the wing = certain death.
the wing snaps off in minutes after it starts to freeze. |

I'm assuming a plane nose diving into the ocean is a result of the engines failing. |
storms over the ocean are really nasty when they are big, because they draw extra power from the ocean and currents of wind that are extensive over the oceans.
two things could have happened:
1. heavy ice caused all engines to fail, one by one.
2. the wings froze instantly when entering the storm system, and one of the wings snapped off in 1 or 2 minutes.
both would lead to major nose dive. |

Can a roughly 500,000lb plane really glide down safely with no power? |
no one knows the severity of the storm. storms cause major turbulence EVEN when you fly on top of them. so that fact that your in the middle of the turbulence + ice + engine failure + any type of system failure
you literally need to start praying for several miracles to happen.
my guess is, you dont fly through the middle of a thunderstorm that is over the ocean and live to tell the tale. |

It's thought that all of them failed when super-cooled water vapor condensed on them. There was a series of electronic transmissions of systems shutting down, including the auto-pilot, just prior to the plane's crash. The systems that shut down were related, in some measure, to those tubes. |
when you enter a storm system, first thing you do, is disengage autopilot, and you try to get out of the storm as soon as possible especially a nasty storm over the ocean.
the fact that its over the ocean and at night, means they were probably not paying attention, there wasnt a lot of good warning signs to be made aware that they are about to encounter a huge storm system,
and once you enter a storm over the ocean, start praying to god, something doesnt fail, or turbulence doesnt cause flutter.
flutter can snap the wing in two based on a specific frequency of oscillation of the wing.
http://en.wikipedia.org/wiki/Aeroelastic_flutter#Flutter
flutter could have happened due to unique turbulence. |

cant open the main door, or emergency door on an airplane during mid flight. they can only be opened on the ground, from the outside.
once you are on a runway inside a plane, you are in it for the ride. |
