It depends. The Denver one [0] basically landed straight away at the same airport 40 minutes later. The Maastricht one [1] circled around for an hour, and landed on a completely different airport. The whole "immediate" and "closest" is relative. Strange as it may seem, an engine failure isn't that big of a deal: the aircraft is designed to fly for hours while missing an engine. However, the aircraft is now in a bit of an unknown state. The pilots need time to work through their checklists, determining what the exact impact is. The airplane might be leaking fuel; it might've lost a set of hydraulics; maybe it's on fire; maybe the engine can be restarted and everything is fine. Landing as soon as possible at the closest safe location might turn out to be hours later and hundreds of miles away, perhaps even at your destination airport!
