I have wondered if an improvement in engines could bring back the 747 as a freight hauler.

I have also wondered if the new US Air Force “Rapid Dragon” system that allows non-bomber aircraft to launch cruise missiles means that a couple hundred 747s should be bought up and modified as a relatively cheap way to deter naval war.

Same with A380s.

Chopping up hundreds of B-52s under Russian satellite view was as bad an idea as USA and Britain sinking war ships after World War I.
It only helps treaty cheaters
