I immediately thought of the Sullivans also. I always love hearing that song about them, what a great tribute to them.
Yes, I agree. And .. their mom (who was a widow) was very proud of her sons and their support of America.
It was this tragedy that caused the military to begin a program to offer an opt out for the last surviving male of the family. I also remember MASH doing a segment on that - and Radar was sent home (as the last surviving male of his family).
At least this family has 2 more sons.
