Missing 777

You can pretty much bet that the ship towing it has a computer monitoring surface speed, direction, drag on the tow cable, length of line out, angle, etc... that puts it all into a calculator that spits out the exact location of the towed antenna to within a few feet of accuracy.

I've done quite a bit of seismic using towed eels. It is very very difficult to know what the fish is doing and where it is in the water. I could not imagine having one on a 6 KM cable. It would probably take half the day just to get it to depth and flying properly.

I flew a kite once....it wasn't that hard at all....but I didn't fly it underwater... soooo.

The chances of the US Navy being able to follow a vessel of interest without the use of a submarine is very feasible.p:thumbsup:

We navigated before the days of GPS. Didn't matter if in the sky, on or under water. All GPS has done is make mental cripples of most.

I don't believe it's a detraction, or even a distraction. I believe it's a fact.

First you search for pings..done...almost a miracle any were found at all
then you seek to locate the pinger on the seabed using the pings...in progress
This requires narrowing the search area...in progress, down from 30,000 square miles at one point to 500 square miles at present
At 3 miles deep in wild ocean waters, given the way sound happens in water, given thermoclines, etc...this isn't an easy task
When the pings stop, and they will soon because batteries DO give out after a while, a radar/visual search is the only thing left
This search is not only 3 miles deep but the bottom there is covered in silt, sometimes over 30 feet deep.
then, let's assume you know exactly where the plane is and that it's not broken open...now how do you get in there and remove two pingers and bring them back to the surface using robots...in the dark with silt obscuring everything. That's hard to do remotely by robot control, even if it were simply in the bottom of the Mississippi river.

You know, if we get over the ineptness of the initial way this was handled, perhaps there is no conspiracy involved in reporting that this task is going to take a while and be expensive...


What's the going odds that as they detract us for a few days/week with "We've detected pinging and are closing in"; shifts to "We need to bring in special sonar/ submersibles to look closer, that's going to take a while"; shifts to "Aw dang it!, the black box batteries must be dead, we can't find anything!" ? - 50/50?

The recovery wouldn't be that tough to do in Hollywood. They are probably passing the first draft script around right now.

I'm gonna go out on an uneducated limb here. I think what's going on now is triangulation. Back in the day Artillery Forward Observers used it.
