The latest deep-sea hunt for Malaysia Airlines Flight 370 ended with nothing found, which is bad news for the 239 families still waiting and raises hard questions about whether searchers have been looking in the wrong place for 12 years.

• Ocean Infinity's underwater robots scanned an area the size of Greece nearly 20,000 feet down and found no wreckage at all.
• The whole search zone was built on seven automated satellite pings from a satellite never meant to track planes, using math that assumed the plane flew straight on autopilot until the fuel ran out.
• Experts flagged back in 2014 that the satellite's orbit wobble was not corrected for, which could throw the search corridor off by hundreds of miles, but those concerns were quietly set aside.
• The seafloor in the search zone has underwater cliffs taller than the Grand Canyon is deep, so a plane could be hiding in a sonar shadow, though that probably does not explain three failed searches.
• If the plane is not where the math said, the alternative is uncomfortable: someone may have still been flying it, deliberately steering it past the predicted crash zone.
• Malaysia, China, and Australia have little incentive to fund another search, and the Ocean Infinity contract quietly expires in June 2026.

Outlook: Without a new search contract or a fresh theory about the flight path, MH370 is likely to stay missing and the case will drift further into administrative silence.
