Any country's submarine anywhere near this area would have certainly heard pings from the black box of a downed commercial jet, and presumably would have reported it. I'm strongly tempted to conclude there was no such pinging to be heard in this area.

How can you be so sure? How loud is the ping? What are the ocean conditions like?
