Airbus planes will soon carry ejectable, floating black boxes to aid in their location.
The article quotes an unnamed spokesman for the European Air Security Agency saying that "the change is generally quick".
I have to wonder if the spokesman understands the reality of rolling out such an option. I know the major manufacturers could design such a system (in a sense it is existing tech). Getting it approved would take a while, but getting every aircraft retrofitted would be a marathon. Such changes are not "generally quick".
