That is one tough old bird
Quite remarkable that the airframe held as well as it did! What you don't see are all the ruined systems / hydraulics /avionics in there.
The remark about frying pans is pretty near the mark. There are quite a few throw away components - from the gear on up - maybe even the wing structure.
The MD - 80 has no explosive bolts - the tail cone is jettisonable if required by the cabin crew (with the rear stairs still retracted) and then a slide deploys.
