In "Musee des Beaux Arts" by W.H Auden, what do the people on the ship do after the see Icarus fall into the sea

They kept sailing.

The poem says that the people on the ship "<span>Had somewhere to get to and sailed calmly on." This supports the fact that no one around really cared too much about Icarus falling into the sea; everyone else in the painting looked like they had more important things to do or worry about.</span>
