If I was one of the investigators who was dealing with this incident, I would be asking to see a copy of this video taken by mobile phone. It shows a complete lack of any decision making by the Flight Crew in a seriously dangerous situation.To fast, to high on the approach, no provision for TOGA and no announcement of an overrun tp assengers or CC.
The cabin crew are not exhonerated from any blame either as their emergency drills and operations should have started once they knew that the aircraft was about to depart the active runway.
This was sheer luck nothing more nothing less....
