Carl shares an iconic family story in a way that makes me feel like I'm a friend of his. His brother's experience in the library would be an interesting story anyway. But, knowing he grew up to be an astronaut makes it all the more compelling. Then, the terrible Shuttle disaster AND the information in the final tag?!?

It stands out for me because it delivers pieces of the story in every element: the intro, the audio and the tag. As a listener, it helps the story really stick in my mind.
