cwatters,
I very much doubt you could work out how it impacted the water from just the wreckage pattern on the sea bed
When trying to model without solid and redundant evidences you are in a risky area.
I suggest people give up trying to work out how it hit the water based only on the wreckage pattern
Time to concentrate in other aspects. It was an exercise and
i finished yet.
Only one conclusion: The existence of light sea currents (combination at many sea levels)
For me it will be a surprise if a/c trajectory (heading) was the one we modeled.
I am not killing the model. Just saying itīs chances are low because the global picture is much more complex and we donīt have enough info. But there are chances.
This crash is unique and can not be compared with others like 961 or Titanic in respect to seabed debris. We supposed in modeling almost instantaneous "stop" as per BEA info.
