The Islamic holy city of Mecca in Saudi Arabia could be a useful area for aircraft to pass over if they were en route to Jeddah from the East or the Saudi capital of Riyadh. However, religious customs mean that airlines are prohibited from entering Mecca and, particularly, flying over the Holy Kaaba. Passenger aircraft are not allowed to travel over Mecca as a mark of respect to this holy site.
Non-Muslims are not permitted to travel to Mecca, as it is a sacred place for the Islamic faith, and the center of the Hajj pilgrimage.
This rule of keeping Mecca for the Muslim population is so strictly upheld that non-Muslims in Mecca can face a fine and deportation. This would include non-Muslims who fly over Mecca, hence commercial aircraft are prohibited.
WHY PLANES ARE BANNED .
1 There is no plane in the Holy city of Mecca.
2. The second reason airplanes don’t fly over the holy kaaba is due to the fact that the saudi government has categorized the city of makkah as a non flying zone for commercial flights for its respect
3. the third reason for not allowing planes to fly over the holy kaaba and makkah is that non muslims are not allowed to travel to makkah. Kaaba, small shrine located near the center of the great mosque in mecca and considered by muslims everywhere to be the most sacred spot on earth. muslims orient themselves toward this shrine during the five daily prayers, bury their dead facing its meridian, and cherish the ambition of visiting it on pilgrimage
