Haven't seen it mentioned but a vote of thanks must go to the Boeing designers responsible for crashworthiness and to the authorities who have been working over the years to establish standards that ensure that passengers actually do survive in survivable accidents.
For this accident, in spite of the impact forces, the door frames did not distort so allowing the doors to be opened, the slides deployed succesfully, the cabin overhead luggage compartments did not break free and collapse onto the pax, seats remained attached to the floor, and there was no fire when one might have been expected.
Well done!
