Not necessarily. Sound does some weird things under water. Temperature inversion layers, density changes, and a whole load of other stuff can cause sounds to travel a long way, and appear to come from different directions.

yes thats true, but the separation is nearly 600 km....makes it hard to believe that cho sound locations could travel that far from the same source.
new development. RAAF P3s apparently picked up another series of signals near to those detected by the ship borne locating device the other day.
The bad news is that the ocean floor at that location is heavy silt. The wreckage may already have sunk into the silt layer and no longer be visible. i wonder if this whole excercise can get any more difficult.

Was is sonar or a metallic detection device used to locate Air France 447? I can't remember. How deep can they penetrate silt?

But remember, they were looking for a while in a completely different area.
Plus, the area where they are looking now has had rough seas and strong currents. If there were debris (luggage, seat cushions, bodies), it would have had time to get dispersed before they shifted their attention to the current area.

I'm really surprised these aircraft don't have GPS Locators that cannot be turned off.
Would make a lot of sense. Guess there will be a push for changes in the aftermath of this incident.
There is speculation that everyone was incapacitated by lack of oxygen. So why not make a transmitter that kicks off when the oxygen level is too low for a human to be conscious, irrespective of whether the crew and passengers have their emergency supply. Also, this is a commercial flight, why not have an alarm transmitted automatically when a plane deviates by more than a set percent from its planned flight path? Make black box recorders "ping" once everyu 5 seconds and have the battery last 2 months.

Because all of that makes sense...
Seems like the co-pilot tried to make a phonecall after the radio went dead. Unfortunately the airplane was out of reach before the connection could be made.

Because where do you draw the line and your aeroplane is now so full of safety features that it is too heavy and is not able to carry anywhere near its useable load? With every incident and accident new procedures come into place, but accidents will still continue to happen and then what? Will we stop flying altogether because it's too risky? Also, with every new addition to an aircraft's equipment fit, a price rise in fares occurs, otherwise, how else is the airline going to pay for all this? Passengers grumble about airfares enough already and flights would become so expensive only the wealthy will be able to afford it. Common sense has to prevail somewhere along the line.
The comment about the ping does make sense, but I bet no one envisaged this might happen when ULBs were first installed in aircraft. As for deviating from a flight path, airliners deviate from their alloted flight paths all the time; the flight path and way points are entered into the FMS (Flight Management System - an electronic device that has information installed about airfields, waypoints etc, it also records fuel useage and other pertinent information, which is transmitted to the Flight data Recorder from the FMS); there is no direct link between the FMS and the flight controls apart from the pilot and if this is a result of the pilots, then what can prevent a pilot going dulally again? In saying that, the likelyhood of circumstances exactly like this one occurring again is very slim, however.
Even if I'm perfectly aware that to find a wreckage around the "Roaring Forties" can be extremely difficult, certainly there must be a point were the debris is concentrated, and form a sort of stream for the currents. Probably U-2 or SR-71, with their possibility to take high resolution photos of thousands square miles, would have proved invaluable in this case. And, in any case, this fact has to be solved, the Civil Aviation in the world over cannot remain the same without explaining in detail how this accident happened, we are not in the Amelia Earhart times.
Of course if there is someone that knows all the things and don't want them to be discovered, thats is another matter of fact, I' starting to believe.......

Satellites were providing images of the southern Indian ocean for quite some time, but whilst threse helped a bit, they also caused a lot more problems. many of the images received proved to be false leads, or unverifiable leads. As angus Houston has repeatedly stated, whats needed is location of wreckage, and beyond that the location of the flight recorder and the cockpit voice recorders. None of that has been found,
This is one of the most difficult searches in history. Lets not mess with that. And assuming that technology will deliver the result we are looking for is a false premise. Nature is as untamed now as it was 80 years ago. There is more chance that we will not find the remains of Maylasian Airlines flight MH370 than ther is that we will find it. Sometimes things happen like that.
The best leads so far, have arisen from mathemeatical analysis, analysis of some aircraft transponder reports, radar and the sheer hard work of the search crews. Everything humanly possible to find the aircraft wreckage is being done, but this still may not be enough.

Here in Northern California, we have large, rugged mountain ranges that can hide an aircraft. Several years ago, they stumbled across a B-25 wreck and crew that had been missing since WWII. It can take quite some time to locate and get to a downed aircraft.
We'll keep hoping the Australians can home in on their finding and it proves successful.

Seems like new developments on this case on Reunion island.
According to the media, it becomes more likely that this is a slat coming from MH370. Let's hope it will give more insight into this mistery.

All flight controls and major sub assemblies on modern airliners are serialized with a data plate riveted to the structure. Unless the data plate was torn off (very doubtful) authorities should have immediately known where that flaperon came from.
