So AnFI, just an opinion, not a fact then.
My estimate, for my opinion, is based on the two electricity pylons seen on the hillside. These can be seen on aerial photography of the region. Using a GIS their position can be obtained and therefore the distance between them. I compared the length of the Apache, obtained from public info, to that apparent distance between the pylons. This allowed me to calculate a scale factor (similar triangles). From that I could determine how far the aircraft had traveled in the last second before the impact. Something like 23m.
