Absolutely. The concern and questions revolve around his mental state, and how he managed to clear screening. IMO, the answer could very well be that he followed a religion that promoted death (Islam) and jihad. This would have no effect on his mental state or ability to pilot a plane. Reports indicate the cockpit recorder shows he did not speak during the final minutes of the flight. Is this the truth, or is the truth being withheld for political reasons? There was also a period during his training in which he was absent. What was he doing? The question I want to hear - was he a Muslim?
Yes, I too want to know ... Till they tell the truth we cannot believe them ...
