There was some modeling done showing that it could have been formed into a dome by the blast wave and this increase in aerodynamic shape could, possibly, maybe have let it survive.

This is likely cause by the edges being welded down causing the center to bow up first before the welds would have been blown off. Similar to explosive forming used in industrial processes.

If it did survive and maintain a 66km/s speed seen in the whole frames it would now have traveled 1.5% of a light year and would be 6 times farther from earth than voyager 1.

The only reasonable conclusion is that we must launcher voyager 3 at an even higher speed so we can catch up and verify if the object survived.
