Malaysia Airlines 777 missing

I doubt they will begin an acoustic search for the black boxes until they have a better idea of the crash site location. I read that the Navy had dispatched a P-3 to help in the search. I wonder if U.S. ASW assets (sonobouy deployment or towed receivers) will be used to search for the black box.

I would expect them to begin searching using all modes from the start. Acoustic signals can travel very far underwater, so I would imagine they designed the pingers to operate at 37.5 kHz as a compromise among transmissibility, distinctness, and package size.

Malaysia has two diesel-electric French-built Scorpène-class attack sub (although the submarine involved in AF447 ended up not being too useful for finding pingers). They also have two hydrographic survey ships and two more coastal survey ships. Which might(?) be available if they're not far away.
 
Are you serious with that site? They have an article about evidence of Biblical prophecies for the end of the world on their front page. Nothing credible happening there.
Next it's going to be aliens, a meteor, Vietnamese forest men and an undiscovered China Sea triangle. Good grief.

Why would you expect that? What is your size estimation of current search area? 500 square miles? 1000 square miles? 10,000 square miles? I'm an ASW guy and the best approach is not immediately obvious to me. Throwing the maximum resources towards finding wreckage seems like the best use of resources to me and appears to be the course chose by the decision-makers in this case.

The detection range is probably only a couple of kilometers, so reducing the search area is critical.

I'd believe a meteor strike over North Korea shooting anything down that wasn't already under its own direct control
 
I'm old enough to be all your mothers!

Kinda doubt it.
