A US Airways flight from LaGuardia to Louisville was diverted to Philadelphia after a passenger alerted flight attendants that a man was wrapping something that looked like a bomb (what looks like a bomb?) around his arm while on the plane. I’m guessing that the man was also heavily beared and praying. That couldn’t have helped.
Had that person (who I’m guessing was from Louisville and not New York, but I have no idea) ever met religious Jews before, s/he would have known that it was just someone praying while putting on Tefillin, black boxes with straps that contain bible verses.
All’s well that ends well, as after the plane was diverted, authorities figured out what had happened (religious Jew misidentified as terrorist), and everyone was sent on their way.
