Maligno, you estimate wrong. By a long way. 11 is the answer you're looking for.
Full Wings is on to something..
It appears there were some GAs by other aircraft prior to the event itself. A tailwind on approach turning to a headwind on landing is a positive shear and leads to increasing IAS, the auto throttle reducing power and a tendency to get high and/or float..
The flightradar data shows a long flare as they encounter the positive shear. Perhaps they realise they are coming to the end of the tdz and give it away, or perhaps whilst trying to get her on the ground they hit nose wheel first causing the bounce..
Positive climb, (150'? possible..) gear up.. Now they've gone back up into the
negative shear.. IAS drops, the aircraft starts to sink..
