Going off of the praying before the planes, take off thing. Um, back when I was traveling a lot to the Middle East, it's actually not uncommon to hear muslims praying out loud. Full volume on the plane during takeoff, and landing and sometimes even see him doing the Bowing in the aisles, as they pray during the flight. As an American, you get a little taken back by the first couple times you experience it. But uh, hey, I'm still here.
