I made much the same point a few weeks ago on a seperate thread. I flew AMS-BAH with KLM and we flew over Iraq.
Okay at FL380 you might be safe from SAM batteries, but what if you lost both donks through fuel contamination, or had a cargo fire, or lost hydraulics, or suffered any one of a dozen other reasons why you'd need to get on the ground pretty damned quick?
Where would you go?
