White men can’t jump, Arabs can’t fly  

I spent 5 years there on a training contract to the UAE military.  Some of what you say is kinda true, but not totally true.  We "passed" too many who should have flunked out.  That said, there were some who I would have shared a cockpit with any time, any place, to include combat.  We used to discuss that among ourself a lot, and the bottom line is maybe 10% (at best) would have made it through USA, UK, EU, etc flight school.
