Can we do the same with MH370? I've got a classmate inside that plane. His family has been deprived of any form of closure or peace regarding his fate.
Around $150 million was spent searching including with high resolution sonar[1]. But obviously nothing was found. The area they're searching is far larger unfortunately.
The precise location of the wreckage nonwithstanding, the fate is pretty clear. Several pieces of MH370 have been discovered washed up along the coast of Africa and Madagascar over the past few years.
iirc when it was missing there was a lot of wild speculation and then someone (maybe it was on twitter) discretely said it was on the bottom of the ocean at some location i can't remember and nothing else. The conclusion was this person was from some three letter agency and knew exactly where it was because of all the listening devices in the various oceans hunting for submarines. They(agency) will never say where it is because it exposes their capability. I think a similar thing happened when that submarine imploded on the way to the titanic.
I remember for the first few days no one was saying anything certain. But once the official reports started flowing after those first few days, they were very certain about the fact that the sub had imploded.
The public wasn't certain, but the search and rescue teams were made aware of the implosion that was detected, that wasn't going to stop an attempt to verify the wreckage.
