> Its exact location was unknown for more than a century, but scientists have now found the wreck of the Mesaba by using multibeam sonar. The offshore surveying tool uses sound waves to enable seabed mapping in such detail that the superstructure can be revealed on sonar images, allowing researchers at Bangor University and Bournemouth University in the UK to positively identify the shipwreck in the Irish Sea.
TIL, the radar is detailed enough to ID the ships without using a submarine.
Yes. You have to be searching the area where the plane crashed though. So far they have only searched the area where the plane did not crash. Uncertainty in the final minutes of flight have contributed to making the job of locating any wreckage very difficult. The ocean is large and deep and finding something as small as a passenger jet is hard unless you can narrow the search area.
Bits of MH370 have been retrieved from Madagascar beaches. The body of the plane itself may have drifted many kilometers away from the point of impact as it sank but it doesn't matter since we have no idea where it first fell other than a general "southern Indian ocean"
Interesting idea, though I suspect a ship of that size didnβt break up as much as MH370 probably did. This would make detection harder since the remaining pieces would be much smaller.
