I have to agree with
janeczku and some others here that an air accident investigation should be allowed to take its course regardless how tedious it might be at times. Shooting from the hip doesn't help anyone - well it might sell news - but in the end the relatives want the truth.
Why the Marseille prosecutor was given such coverage with his verdict reached after some 48 hrs is astounding. However with such high number of causalities and so many Wikipedia aviation specialists around it is not very surprising that pressure is mounting to find someone to hang or a country to flatten like after 9/11.
Having seen aviation bodies and manufacturers lobbying over the decades for passengers to accept a certain ++ on their air tickets so that FDRs can be introduced on a wide variety of commercial aircraft it is rather more surprising that a prosecutor sees no need to see this valuable data before coming to a conclusion.
After all it took the same French authorities over two years to find the AF 447 recorder at depth. And three years to complete the investigation report. They must have been glad they did spend all that time and those millions in order find the real cause of the accident. And consequently introduce recommendations that surely will help preventing similar accidents in the future. Needless to say that even here on PPrune many had it wrong until the FDR in combination with CVR data was properly analysed.
Only then would it be OK in my opinion to unleash experts like NYT, Bild Zeitg, R Quest, P Geller and have a go at who/what ever secures the most readers, viewers or listeners: young FOs, old Capts, the gliding club, the ex girl friend, shrinks, pharma industry and of course the mosque in the next town.
