1. I suggest that you clue up about Saudi pilots who have been part of the "train foreigners" package the USN has had in place in Pensacola for decades. (We also have had boatloads non Arab sorts, like NATO allies and Brazilians, reaching back to well before I ever showed up there as an ensign while Carter was president ...)
While a few get with the program and did well, far too many were in that billet due to a family connection and prestige.
Nearly two decades ago I was confronted with an asylum request (had to staff it) from one of these "not so right stuff" candidates. This non performer, having been disenrolled due to lack of performance, was asking for political asylum since he was afraid he'd be killed when he got home due to the shame he caused his family.
We eventuall punted that one off to OLA at the Pentagon, and they handled it).
2. As to this case,
this little Saudi Snowflake has no business in an aviation squadron, if this article is to be believed.
Got his little panties in a wad over a call sign / flying name. That one's pretty mild compared to stuff I saw all over the fleet.
Do you accept that as justification for shooting up a classroom, or not?
