According to news from Saudi Arabia, approximately 200 mosques in Mecca are not facing the correct direction. Worshipers concerned about the validity of their prayers have been assured that their prayers were valid. Many of the mosques are more than 50 years old and the mis-alignment was discovered due to better measurement technology (and someone looking down from a high rise apartment).
I wonder if any of them were built by the Bin Laden Construction Company?
It makes me remember the story about a major US construction company who had their plans for a Saudi offshore quarters building rejected because the toilets happened to be oriented tewards Mecca.
