It appears to me that for all the rushing about (which was appropriate and neccessary if there were any surviors or surface debris to be found at all) the somewhat grim reality is:

1) hydrophones heard it implode at the same time it lost contact

2) it took until early 6/22 to get a deep-diving ROV on site

3) once the ROV got to the bottom, it swiftly found the debris from the implosion as expected
