Assuming that the data behind the charts is good, that is some fascinating work. Since the difference between the July 4th flight and the July 6th flight starts at 4 NM out it seems as if the NTSB would want to talk to the pilots of the July 4th flight to find out what those pilots were doing...thinking... differently than the accident flight because it seems that moment is where the accident crew got behind the airplane.
Taken holistically, what leaps out to me from those charts is that the difference between a hard landing and an accident is a game of inches, a matter of a few brief seconds. The accident crew was off but they were not off by much.
