Or hoist cable cut when the plan was to activate the floats? (I can see that happening, being prepared for hoist cut during the hoist ex.)
From memory, on a similar type the hoist cable could not be cut unless out at least 0.6m.
On the video the aircraft is initially inverted on the seabed, then the footage changes to it upright but still on the seabed. At 1:13 to run you can clearly see the aircraft now upright and the twin hoist is separated from the hoist support strut with the outboard hook missing. It is possible that the missing hook was ripped off when the hoist mount was damaged. It is also possibly that the hoist frame was used to right the fuselage, though why they then attempted the fuselage recovery using the undercarriage I cannot guess? Possible the video is not stitched together chronologically?
