I’m beginning to think the captain may actually have decided, when the engines began to quit, that they'd never make Rio Negro, that a crash was inevitable and that his only option was to drop all the anchors and do so at the slowest possible speed
Emergency landing in the field , at night ?.. no way , except going for an illuminated motorway, but in a 146? I do not think that was in their mind setting. illogical, but OK nothing was very logical in this accident.
Flying at slowest possible speed = no way to avoid sudden obstacles or to stretch the glide if too short. No-one would do that in an emergency .
My guess is that they realized they would soon loose hydraulics and dropped everything they could and thought they would make the runway. They did not see/ count to overfly a hill at 9000 ft on the way ...looking at the pictures of the accident , they just missed 20-30 feet.
