Missing 777

Triangulation works fine when signal propagation travels through an unchanging consistent medium.
Stratified sea water of varying salinity and/or temperature reflect or "tunnel conduct" sound. Even "super conduct" or attenuate signal strength just by moving the pinger or hydrophone a few hundred feet..

The sensitivity of US and Soviet listening devices? As the US has been searching for MH370, they can tell it was curry night on a Chinese ship 200 miles away.

Maybe 100/50?

You talking about eyesight?

My bad. Thought this was the ophthalmology thread.:laughing:

Glomar Explorer goes mining again?

Those inertial gyros are spinning for a reason.

Straight lines but no distance!

Yea, I was thinking that too... maybe we can find the next generation patriotic eccentric billionaire to resolve this for us.

The Explorer is still around, and if this info( GSF Explorer - Wikipedia, the free encyclopedia ) is up to date, she's in the Bay of Bengal.

Looks like its been converted to more of a drilling rig now. Wonder what happened to the grapple?

The grapple broke. It was made out of the wrong alloy that was high tensile but brittle . Needed to be to have some ductility at 32F.

All GPS has done is make mental cripples of most.

I don't know, the way it never directs me along the easiest route has exposed me to lots of places I might never have seen if I had used a map. :laughing:

 

[Soundguy]

yep.. gps makes you appreciate 4x4

Friend of mine owns a tow business in rural Missouri. He loves GPS. Makes him a LOT of money.

I used to scoff at GPS and make fun of people for not using maps but if you think about it a decent gps is really just a big collection of maps in a convenient box. I've seen plenty of in accurate maps in my day.

Good point, the GPS is very accurate, but the mapping software that is displayed and you are following are only as good as the maps themselves and the algorithm that calculates your path.

I've always been amazed at the accuracy of the maps and the car icon showing where I am on the road. Sometimes, it will not understand construction detours.

What are the chances that a group stole the plane and then tossed a couple of black boxes overboard from a boat out in the Indian ocean just to throw off the search for runway landing points? Even if they find them, I'll bet they are 'empty' of conversation and aircraft damage flight data. These pilots knew what they were doing. I prefer the " 'dirty' bomb transporter needed" Craigslist ad theory myself.

Hollywood has already signed up for the mini-series. If they would use it while Congress is in session, I could probably go a long with it...

A 727 is easier to convert for nefarious use. Lots of them around waiting for buyers. I think.?

 

[texasjohn]

Watch it, ZZ, if you are trying to be funny, it's not. In fact, it sounds like you are in support of a terrorist WMD attack on Washington DC. Suggest you recant/remove the post.

777 has three times the range of 727 and much greater payload. However, 727 has short field takeoff and landing advantage, is smaller, and easier to hide (relatively speaking). Also, you can refuel a 727 over the wing, while you can't with a 777 (that I know of). Anyhow, I wouldn't think anyone could hide a 777 that easily for that long. But it would make a good plot.
