The third-person point of view is a type of narrative that follows multiple characters and narrative arcs. Depending on the number of characters the narrator follows in detail, the third-person narrator can be:

omniscient, or all-knowing - This type of narrator has insight into every character’s thoughts and feelings.
limited - This type of narrator is focused on a single or several characters and is aware of what only they think, feel, or do.

Thanks to the third-person point of view, we get to know what both Icarus and Daedalus felt as Icarus plummeted to his death. If the story was told from the first-person point of view, we'd only know what one of the characters thought and felt.
