"In a scattering of graveyards around the U.S.—one of them at Arlington National Cemetery in Washington, D.C., the others in New York and Michigan—are three bizarre tombs, each of which holds a lead-lined coffin buried extra-deep and covered with many feet of concrete. The graves hold the still highly radioactive remains of three young servicemen, named Richard Legg, John Byrnes, and Richard McKinley, who died in this country's only fatal nuclear accident—a total fuel meltdown that occurred when an atomic reactor went suddenly and disastrously critical."

Simon Winchester reports for Newsweek March 20, 2011.
