Dotticom,
Could you elaborate a bit more?
So far this accident is kind of mysterious: it's said that CVR doesn't have conversations from the last flight, only from a previous one; and that the plane didn't had a FDR.
And the only audio available, so far, was from a Brazilian site (radarboxbrasil) that captured audio from the pilot-tower. But the conversation with the tower was a regular one, just stating that they missed the approach and would follow the procedure for that airport to try it again.
