As mentioned earlier, the B757 incident at London Gatwick some years ago, where the operator thought they knew better than Boeing and modified their QRH for Left HYD system failure, meant that the ABS was incorrectly selected for landing. The aircraft lost control directionally when THR RVR was selected and the aircraft departed the paved surface then regained it after a while.
It appears similar to this event (no ditches at the side of Gatwick’s runway!).
Anybody have a link to a report on the Gatwick incident?
