Oh, those wild, wild speculations! Noone has seen the CVR transcripts, the black boxes havenīt even been opened yet, most bodies still havenīt been recovered, and we get, in these posts here, everything from "urgent third call from ATC" to "meals being served, therefore the Russian crew did not respond". I am somewhat disappointed about the unprofessionalism of many of the posts in this thread.
Having said that, I must admit I am not a flying professional. But is there not a difference between "rumour" (this forum!) and mere phantasy?
