I said to myself, lets see 'Mekka' on Google Earth and explore a little bit.
So I typed 'MEKKA' in the Search-Field, and see by yourself, what choices I got. :D
if you really don't spell it properly, thats what you get. I mean, at Google, they should know that, many people use this way of spelling Mekka. But you must type 'Mecca' or 'Makkah' to get the right request !
