Air France Flight Missing

[FlickerFade]

You'd think that a P-3 with sonobuoys - ones that can find a sub that is trying to hide - could find a CVR and FDR that wants to be found.

Any one have info on that aspect?

sound travels in different channels in water based upon temperature, pressure, and salinity. Getting buoys in the proper place to detect an object 10,000 ft or below is incredibly hard. then, getting a location on the object is harder. A submarine is way more reliable given its ability to change depths and having more sensors, but even a standard sub can't travel that deep.

It's just a very tough scenario.

Most of what I know is from reading "Hunt for Red October," so not much. Any idea how deep towed arrays for the destroyers and subs go?

I'm not sure about boats

but they would be much better prepared for a sustained search than a plane, their limit is in their ability to transit a large search area quickly.

Do subs have pitot tubes that work in high humidity???

So it's been like five days since the last comment -- and that was me. Has this tragedy fallen off the radar screen in deference to our own issues here in the US? Do we really care?

Brad and Angelina might be splitting up. That overshadows everything....

I'm out of country so to speak-BBC is covering the Paris Airshow 100th Edition and they are making point of how EADS is carrying on about the outstanding safety record of their aircraft...in between reports about the floating Vertical Stab-so it's not off the radar world wide at least!

Most of that ASW stuff is done in the first couple of thousand feet of water where subs operate. They can use the bottom to bounce sonar waves off of, but aren't looking for anything on the bottom.
I suspect special equipment towed at deep depths will be required. Just my two cents.

This new item today form MSNBC indicates the likelihood of an breakup before impact due to clothing being torn off and the nature of the injuries on the recovered bodies.

Nova: Crash of Flight 447 premiers on 2/16/11. You can watch it now on Netflix.

Although the "black boxes" haven't been found, Nova did a pretty good job of coming up with one compelling reason for the crash.

If you lost your airspeed indicators at altitude, would you know what thrust and pitch attitude to maintain?
