Unless I am mistaken....did not one of he pilots state there was a loss of engine power just prior to the crash in Afghanistan?
As the CVR and Data Recorders were not recovered....it would be hard to state with definity what the engines were doing would it not? Just saying!
So one's suggestion it was all Pilot Error might be a bit hard to substantiate in my opinion. When a General Officer is willing (in this political Air Force extant) to state publicly he was pressured to change his findings (during what is billed to be an independent and objective investigation) I would have to view such final findings with a jaundiced eye at the least.
