Wow. That escalated quickly. It has nothing to do with the fact he was Muslim and everything to do with the fact that there were no attempts to contact other planes or atc for help. I do not appreciate your false assertion and encourage you to retract your statement.
I am not an expert in the 777 electrical systems but the two minute delta between the last radio transmission - where there were no audial warnings and the pilots were calm - and the transponder ceasing to transmit seems unreasonable for a catastrophic event to take out these systems.
