KNIEVEL - There are known facts. Such as the fuel remaining was located in the MAIN TANK and the SUPPLY tanks were all but empty. The Rotor RPM decayed beyond that what was recoverable.
The problem is how did these situations arise? There are known causes to get to these situation but we do not know what exactly occurred to deliver them. In my opinion, we will never know given that the helicopter did not have CVR/FDR.
Without the flight recorders major pieces of the puzzle are missing.
So not conflicting reports of what happened. What happened is relatively clear. The WHY is the bit that cannot be fully understood or answered.
I believe that as the inquiry progresses it will become clear to the board that without CVR/FDR data a complete understanding of why it happened will never be reached.
