Because an Arab terrorist would not be familier with flying a American jet...
I think my friend you are deluded in your opinion, you started off weak to mediocare, and now fair as poor to pathetic on the intelligence scale you match a slug.
The arabs and Muslims and any other breed I have missed that you may term them as are very intelligent, patient people. They will train for a higher goal that you or I could never ever follow.
They will dedicate their lives to be perfect at something in their opinion, at the same time they will sacrifice loved ones if it is for the benefit of their culture as they see it.
Look at the doctors that had a go at being suicide bombers in Scotland or are you oblivious to this?
Look at the IEDs they design, cheap and more effective than anything the Irish have made.... I could go on but you are in no way understanding.
Emirates airlines I guess has no arabic pilots???
