My Great-Grandfather was eight years when Custer fought at the Little Big Horn. He lived long enough to see the B-52 go into service.
Have to comment, amazing.
My Grandfather hunted passenger pigeons when they darkened the sky, he too saw the B-52 fly and a whole lot more.
My Great-Grandfather was an Oklahoma Territorial Marshal for Judge Parker but he did not live to see much beyond the Depression.
