Here's one for you conspiracy theory lunatics. Make sense of these two questions after watching the following video:
 

 
Q1: How is it in the US when a crash like this occurs the TNSB pours over findings for months even if they're 99% sure of the cause because of checks and balances in place with cash investigation protocol, yet the French use a "prosecutor" to release the statement people hear about a mere 2 days after the incident.
 
Q2: The timeline the "prosecutor" mentions goes into minute details like explaining that the cockpit recording picked up minute details like the co-pilot's steady breathing up till the end, the Captain getting out of his chair and exiting through the door, pounding on the door and screaming yet not a single mention of any interphone annunciation or emergency door override annunciation warnings. Even if the co-pilot overrode the door there still would of been annunciation on the emergency door pincode attempts.
 
Either this "prosecutor" left out critical information from his statement, or his sequence of events don't mesh up with Airbus training videos on how door mechanics work in the A320.

    Found that someone dug up the A320 manual and it states the lock position for the CDLS if engaged suppresses both the keypad and keypad attempt annunciations for 5 minute periods of time. Sounds like a bad design decision if it's suppressing attempt annunciations. Those should happen even if locked out to document the attempts and to make the cockpit crew aware of the attempts.Eh, hindsight is 20/20 I guess.

    Speaking of bad design decisions - who wrote the code that allows the autopilot to fly to an altitude below ground level?

    I read that  the plane was in commission for at least 24 years old. They say their fleet has an average of 9 years. So could that be an issue for the plane to crash and go down?

    I said ground level, not sea level... or do the Dutch have underground airports?

    The French say the pilot of the aircraft deliberately caused the crash. This is quite unfortunate and my heartfelt condolences go out to the families. Several airlines have now adopted new cockpit rules in light of this tragedy.

    This is all very sad. I feel for the families. Although many facts have come out and will continue to, in the end we will have a report on what was found. We can judge things based on that. Does not look good for the co-pilots legacy.

    1 Our government likes to keep secrets from us.
    Then after a while and time pasts, they ask us "At this point what difference does it make?"
     
    2 Maybe the pilot did not have time or did not think to punch in the code. 
    Could be he was punching in the wrong code.
    They did say things are preliminary and facts can change.
     
    3 There was somebody on that plane that someone somewhere didn't want alive anymore.


    Added one. I honestly don't care WHY the plane crashed, it just makes me mad that it DID crash. It really makes me mad that the pilot wouldn't have someway of forcing himself into the cockpit in an event such as this (or even lets say, the door gets stuck or something by accident and the pilot is locked out?).

    There's a code the pilot had to enter if he gets locked out. The only way that won't work is if someone inside the cockpit is overriding the code. Throry being if a terrorist had the code, it gave the pilot a way to keep them out.

    I mean, odds are the guy initially in the cockpit is the good guy... right?

    Really it's a catch 22, and we can't fault the system for working as it was designed.

    What would have been helpful is if they adopted the FAA standard practice of always having two crew in the cockpit at all times, even if it's just a flight attendant.

    100% sure that will change... nowish.

    Great point and I totally agree.

    Well what I said was a joke, although most of the Netherlands is below sea level.
     
    But from what I understand, there's no system for calculating altitude above ground level on the fly anyways. On approach, pilots communicate with ATC to get that information for the specific airport, but they don't have any type of system in place to calculate ground level between airports. Altitude is simply a conversion of atmospheric pressure calculated from average sea level, but has nothing to do with ground level. For example, if you're flying 1000 feet over Mount Everest, your altitude reading is still 30,000 feet. Without knowing your surroundings, you're essentially flying blind, which is why many aircraft crash into mountains when they don't follow proper flight paths.

    I don't wish harm to anyone in general. I am tired of people who want to take the easy way out, and want to kill others. If your intent on ending your life please leave others out of your decision. I would hope you would reach out for help ,and maybe find a solution. That's something that has always bothered me. Life is a journey there is good along with bad.

    They have depth finders on boats that tell how deep water is, why wouldn't that tell you how far off the ground you are? Point it in front of you why wouldn't that tell how close a building is? They have range finders for hunting that could tell how high off the ground you are.


    Depth finders work using sonar, which only works in water. Range finders use lasers that reflect off distant objects, but have a limited range (typically of around 1km) because the beam starts to scatter as it travels through the atmosphere. 1km = 3280ft, which is not even remotely useful when your typical cruising altitude is 30,000ft.
