To one generation, the indelible image of John F. Kennedy Jr. was taken on his third birthday.
A little boy with a powder-blue coat and bare shins, standing in front of a wall of black-clad mourners. One hand raised to his forehead, saluting his slain father's coffin.
To the next, it was a photograph taken at a party after the 1999 White House Correspondents' dinner where he'd hosted a table as the Editor-in-Chief of George magazine. Jacket removed, he sits in a black bowtie and vest, his lips planted on the cheek of his wife, Carolyn Bessette-Kennedy, who's nestled in his lap.
Each carries tragedy. A little boy too young to grasp what he's lost; a 38-year-old man unaware what he's about to.
Just three months after the party photograph was taken, John F. Kennedy Jr., Carolyn and her sister, Lauren, were killed when Kennedy's light plane crashed off the coast of Martha's Vineyard, Massachusetts.
The accident raised countless what-ifs about the potential of "America's son", questions that are being pondered again today, as we approach what would have been his 63rd birthday on November 25.
