The visual facts as can be derived from the recovery video as far as I can see:
- The aircraft fuselage and undercarriage was intact on the seabed and the only damage seemed to be to the MRBs,
- The MRBs damage was consistent with a forced stop while turning at speed
- The float system was not deployed
- The TRDS was intact but the TRBs were mostly undamaged (in comparison to the MRBs)
- Main undercarriage torn off during recovery operation
- Aircraft dinghy's were not in their stowage locations in the front of the sponsons
What can be logically deduced from above and other details of the incident:
- Water impact was not at 'high' speed either vertically or laterally (fuselage largely undamaged and occupants physically able to conduct emergency exit)
- Fuselage remained on or very near the surface despite lack of floats, for sufficient time for the 6 crew to evacuate
- MRBs impacted the water such that the head had near stopped before the TRBs impacted the water (nose down or sideways roll?)
That's all I have got.
