Well, you could ask the same about Amelia Earhart. People are just curious about that sort of thing, that's all. They want to know what happened. What is to gain? For those writing the stories that interest people and reporting on those stories, what they gain is their weekly paycheck. They wouldn't write about it if people weren't interested. By writing about it, they create more interest...thus keeping themselves employed. ;-) That's what's to gain!
