Thanks blueloo, that's correct, I was referring to Georgia USA, which only has a highest peak of 4784 feet. (Isn't Google handy!)
Where as the emergency descent took place in Georgia, the country, which has many peaks above 15000 ft and some up to 17,000 ft.
Mike,
There were quite a few posts earlier on the thread which have now been deleted, by people assuming I meant Georgia USA and not Georgia the country. It seems my reply to their now deleted posts makes that last sentence seem a little confusing out of context.
