We have found two versions of the telemetry data informally relayed to us. One version indicates that the engine lost power due to fuel interruption from the high g level. Depending on the geometry of the fuel system in the Ghost, it may be possible to estimate peak g required to cause a fuel interruption.
Interruption of fuel can occur due to pump inlet conditions or pump outlet/engine inlet conditions.
Was the fuel pump on the Ghost a centrifugal pump or a positive displacement pump?
Was it tank mounted or engine mounted?
Is the fuel source a wing tank or some other tank?
Is there more than one pump involved?
