In the flying school I was working at, the school had no say in who the Saudi students were, they were selected on their side of the puddle. Usually they had a daddy who was a colonel or a general, and one of the students was from the al-Saud family, but a long way down the line for the throne.
The majority were only there for the status of being in the military and the higher status of being a pilot. Passing the course was low on their list of priorities, compared to the delights of living here outside the sandcastle. Graduation presents from their families included the odd Ferrari.
