I think it was five years later when Bobby's body did the cross country train ride.
Thanks for correcting me. Those are long-ago memories, and are kind of conflated in my mind, I suppose. They're kind of all in what might be called my "disaster folder" of childhood, which also includes a bunch of men standing on a hotel room balcony pointing at a point above them and and in the distance, an image of Bobby Kennedy looking at the ceiling, and the voice of Jim McKay saying "they're all gone."
I remember watching JFK's casket being unloaded from AF-1 on live tv, though. I also remember what seemed like endless days of coverage of nothing but train tracks when Bobby died, and MLK's casket in an old farm wagon.
