Normally you wouldn't get anything official either, in the days after the crash.
You'd certainly get a press conference detailing what is going to be done, asking for calm and the time to let the investigators do their work without any ridiculous speculation.
These investigations usually takes weeks-months, sometimes even years before the official report comes out.
Yer, I think you need to re-read back what you've written there, comprehend what it means and then have a look at the conclusions the prosecutor has come to before such an investigation has been completed.
Of course, if they had kept quiet for months, and then came out with the voice recorder tapes, people like you would have cried conspiracy because it took so long.
No. I don't know where you get that idea nor why you're winding yourself up in the word 'conspiracy'. Certainly, in the absence of some or all of the data it is essential the plane is reconstructed as much as possible, and given the state of it and the wide area of wreckage that will take some considerable time - as it always does. Without matching up the state of the aircraft, what has happened to it and retrieving any data possible any voice data useless.
It's always amusing to me that anyone who questions anything is somehow a 'conspiracy theorist', and then anti-conspiracy theorists then ironically become the biggest conspiracy nuts of all. They start throwing stories about aliens and other stuff into the mix to try and make it seem all so unbelievable.
