Thank you RegDep, but I found the chart difficult to read (and the report horrific...). None of my (somewhat old - 2003) USSR 2xNDB plates have the 'ATC descent' bit.
I need to rewind here:
Where is the evidence for their being 100m high at the OM?
Where is the evidence for 6.8m/sec?
Do we have the FDR?
What if they WERE 'on glidepath' until the fatal dive into the valley?
