I am quite surprised that no one has thought of making some basic computations on this flight :
At an - estimated - OEW of 42,000 kg
- an estimated traffic load of 12,000 kg (124 passengers plus some freight )
- a reported 6,000 kg of fuel remaining (2,000 USG )
The landing weight is in the vicinity of 60,000 kg

At that value, the required wet runway length - from the *in flight performance* charts would be 2100 meters

The final approach IAS would be 130 kt which translates into 138 kt TAS and a ground speed of 148 kt with the 10 kt tailwind.

With the above in mind and considering the available runway length, the displaced threshold, the reported *slippery* surface, and a challenging circling approach with marginal visibility, I would say that in order to remain inside the runway length, every aspect of that landing had to be perfectly right and the margin for error close to NIL.
I might add that the influence of operating reversers is worth some 8% of the required landing distance, i.e some 150 meters.

Conclusions ?
