How about the supposed violent ups and down from FR24 data, are they spurious or real? Could the jack screw fail and the HS go uncontrolled? Now the damage to the VS looks like happened in flight and not at the ground impact... Also no wonder the APU/tail cone separated...
Digital data can not be spurious. There is a data integrity check to avoid garbage transmissions.
These are actual sensor readings in FR24. But the question is what caused sensors to give such readings.
One explanation could be, that sensor ports were over or under pressurized due to abnormal flight attitude and air flow direction. Plane was not flying anymore. It might have rotated somehow for example.
