Firstly, hats off to both crews, great job to get everyone on the ground safely given the sh!t sandwich you found yourselves eating.
This incident confirms us as being in the ranks of the aviation third world , and has all the hallmarks of similar incidents for example the
2010 Polish Air Force crash in Russia, which didn't have a "good outcome".
Thankfully both aircraft were 800's with high accuracy nav systems. It could well have been a different outcome with a steam driven non-GPS model.
