I see TE flaps in, or almost so.
Imagine a crew trying to make a field with insufficient thrust, understandably they'd be keeping clean conf. and speed for max L/D. On the other hand, a pre-determined ditching is surely flown at the slowest Vref you could get.
Estimating 210 and 130 kts for the two cases, with an impact weight of 49 t,
the kinetic energy equation gives 270 MJ and 104 MJ respectively.
No need to look any further why the same metal buckles and bends once but breaks and tears on a different day.
The involuntary ditchings discussed above were all at approach speed, to my understanding.
