Malaysia Flight 370: 'Optimism is fading away, ever so slightly'
The optimism that bubbled up over the weekend when an Australian navy ship detected pulses that appeared to signal the nearby presence of Malaysia Airlines Flight 370's so-called black boxes had subsided somewhat by Tuesday, as continuing listening efforts yielded nothing. Searchers are still scouring the waters, but their optimism is "more cautious," said U.S. Navy Cmdr. William Marks. "As hours pass," he said, "our optimism is fading away, ever so slightly."… (www.cnn.com) Mehr...

No black boxes have specific pinger identifications so a pinger broadcast is just a pinger broadcast.
They are all serialised and matched to heavy aircraft and manufacturers (Mainly Honeywell) have records of all their wares. But until its recovered (Hope so for both) and the serial numbers match 9M-MRO - yes your are right its just a pinger broadcast.

I guess what Ron Lorenz seems to be hinting at is ,
what if the hackers show their skills and fake/duplicate the signal ?
During W W II such ploy of fake and/or interfering signals was used very often by using radio signals. Including fake radio stations with same duplicated or say overlapping frequencies !
In today's time it can be electromagnetic kind and in binary code !

Not unless they can stand the pressure and darkness and get their laptop and broadband modem working in 4500 meters of water. LOL!
There is a three part news item in today's news paper in New Delhi, India
" In race against time, ship hunts for more jet ‘pings’ "

First part , mainly on
' ... . Once the beacons blink off, locating the black boxes in such deep water would be an immensely difficult, if not impossible, task.
If, by that point, the US navy listening equipment being towed behind the Ocean Shield has failed to pick up any signals, a submarine will be deployed to try to chart out any debris on the seafloor. ..... '
The second part , about the sonar ping locator torpedo ! The one that can go to depths of 4500 metre and run on a 20 hour mission !
The third part is a bit hurting type , " Cost of MH370 search reaches $44m " .
Though, prima facie, an informative piece, but the style of presentation seems annoying in as much as that to question the costs involved in this recovery mission !
I have been asking myself time and again a familiar question. What cost of inventions and discoveries ? And what cost benefit ratios, be it the short run or the long run ?
I doubt if such an analysis can be made validly for any new creation or discovery. Benefit of such inventions or discoveries can never never be fathomed instantaneously, in most cases.
Space research ? Moon to beyond the Solar system travel ? Why ? To what end gain ?
Difficult to gauge today. But gradually and indirectly we find uses of the development of tools and technology !
Same can be true in this case.
After all what will be gained by locating the BB ?
Causes of the crash ?
Yes but that's not all. We will be able to prepare a blue print to prevent similar happening for all time to come for each and every flight, be it commercial or private or even military application .
Let us wish the search teams well.
And keep our chin up .

Just saying mind you, what if the plane was highjacked?
and flown to god only know where? How would you throw off
the searchers? One way would be to take another black box
with a pinger on it and throw it off a boat a long ways
from where the plane was headed. The Sat.signals from A
plane, not necessarily the highjacked plane is all they
have to go on! I don't think they can tell one black box
from another?
