Also significant is that on the landing in the inbound sector it sounds like they planted it on and really harped on the brakes, for whatever reason. They had a subsequent brake overheat and it was all part of the discussion captured on the CVR about pallets that had shifted and broken some straps.
This could have been the catalyst to what happened on the next takeoff. The broken pieces of hydraulic tubing found on the runway do make you wonder. I guess the cargo impact on the rear bulkhead was substantial enough to clarify as a "crash" which severed or compromised the CVR and FDR power, making them stop recording shortly after.
I wonder if the QAR recorder was destroyed beyond use. I know many of the cockpit parts where, so it probably was. I'm sure this came up during the investigation but I did not read the entire report.
