Did the google earth ruler give you statute miles or nautical miles? Since aircraft speed is measured in nautical miles, that's the unit of measurement I used.
The way we normally measure distance is statute miles, I would not complicate matters by using clicks or nautical miles. However, I do see your point.
In any case, I think we'll find that they launched from Pakistan, Afghanistan or one of the northern "stan" nations. Anything closer would be preferable.
