Even if they do find the black boxes, they won't provide as much useful data as would normally be provided because they are on a 2 hour loop and the flight was off course for what - 8 hours?

Also - nothing has been brought up about the fact that all communications with the plane went silent prior to it diverting off course - that would leave the possibility that the flight and cockpit voice recorders also went offline (intentionally done or not) at that same time, so there may be nothing of use at all on them.

The CVR is the only item that loops after 2hrs so the recorder would provide the last two hours of any speech made made in the cockpit. The CVR (cockpit voice recorder) and the DFDR ( digital flight data recorder ) are never online. They record what happens on the flight and will be inspected in the event of an accident or incident. The DFDR records the last 25 hours of flight data and not 2 hours.

Just thought I would clear that up.

The ELT starts to emit in the event of a hard landing or an impact (accident). It can be switched off from the cockpit in the event of the initialization being from a hard landing. The built in ELT transmits to the satellite on the 406 MHz frequency which is monitored by Cospas-Sarsat system.It also transmits on the VHF guard frequency of 121.5 which is fairly ineffective as it must be close enough to another aircraft, ship or ATC facility to be picked up and does not in any way provide accurate information of the actual whereabouts of the A/C but rather an area. Generally the closer you are the stronger it is.

The 406 MHz transmission should be located within 6-8 hours of the initialization of the signal.

Every thing I have seen on the news is BS

And I'm certain you base this opinion on your years of experience with sonar and other acoustical devices operating in an underwater environment,right??

Did the Air France ELT send out any signals? I don't recall hearing anything about that. In addition, how well would the ELT transmit once it was exposed to and sunk beneath sea water?

I can tell you for a fact we just bought a new ELT... As stated the VHF is about useless but it is sealed and is water proof so if in fact the airplane is in the water it still would have been found via satilite...

elt is all but worthless under water,,the signal i believe is too weak,,not designed for that,,,just my two cents,,i think the plane landed on dry land and the black boxes where removed and flown to the south indian ocean and dropped off,,this would send all recovery crews in a far off direction looking for a plane that isn't even there,,no debris field too long to find a pinger,,all sounds like we better be watching our backs for some time

I'm curious what the attenuation of 400MHz signal is underwater. I'm thinking that it may not penetrate 2.5 miles of water.

I saw Elvis walking on the moon recently.

And what might I ask, were you doing on the moon Alice, when you saw Elvis there?? I hope you weren't visiting the Lunar dispensary.

I had a quick flick through and don't think this one has been posted, make of it what you will...

I wouldn't put it past the people really in power to pull so.ething like that, but we'll never really know.

That was interesting reading....

Crazy how accountability only seems to work in one direction

It's now a year later.


Do you still hold to your ridiculous theory?
