Malaysia Airlines 777 missing

This whole thing is just seeming more and more fishy... I am seriously beginning to wonder if some country (red flag with one big star and four small ones) who is getting more and more aggressive towards non red flag vessels in the South China Sea mistook the flight deviating off their assigned route as suspicious and mistakenly took military action. I hope my crazy conspiracy self is wrong though...

Iran Air 655 (shot down by USS Vincennes) comes to mind. And, of course, KAL 007 (shot down by Soviet Su-15). Intentional or accidental it doesn't matter.

Not to threadjack but an amazing post just went up on Digg that is all over the outdated technology that is used by flight crews, and that passengers have access to better equipment in the back. His point and others - made timely by the loss of MH370 - is that if aircraft broadcast FDR telemetry in real time they could be found more quickly or assisted during an emergency.

The guy sounds nuts, and claims to own a Citation, and intersperses tripe with facts.

No debris after this many days just eeks up the creepy factor.

Or they simply have not completed the search in the one area they are looking in, or they are searching the wrong area altogether. I am really wondering about the latter scenario right about now.

Is it possible hijackers forced the crew to fly low (below radar coverage if that's even possible) and forced it to land somewhere remote? Or do I just watch too much TV? I just can't fathom why there is NO evidence of a crash for so long.

Where exactly would be a location so remote where you could fly and land an aircraft of that size with no one noticing and completely undetected even by any military entity?

Something I think about when flying over the Persian Gulf.

Here's where the Vietnamses are searching today (yesterday).
18484-d8967d15fa0c7d29a6553082289e85f0.jpg

Quoting from the Google Translation of that page:
"In particular, the Malaysia has 6 planes, 6 ships, China has two aircraft, 14 ships, the Philippines has one plane, three ships ; Singapore has 1 C130 aircraft, and Vietnam have 3 planes, 6 ships."

Did some quick math (you aerial survey guys feel free to laugh at me):

One of the aircraft deployed by Vietnam in the search is a DHC-6 on floats (so, cruising at 120 knots?). At 4,000 feet it seems like a lateral search distance would be limited to, say 8 nm for visibility. So that plane can cover 1,920 nm² in an hour. Reality is less than ideal, so 80% of that is 1,536 nm² in an hour.

I calculated the area of that upper right hashed area marked 09/3 as 3,525 nm², so the DHC-6 should be able to search that in about 2.5 hours. If you go long to 3.7 hours, the swath can be reduced to a 5 nm lateral.
 
Do the "black" boxes not have any type of location devices on them? Isn't that how they found the boxes on Air France?

The FDR & CVR each (or two dual-function units) both have pingers. That's what is a little confusing to me. The things are designed to begin operating when they get wet, operate for at least 30 days, and are designed to be found acoustically. The gulf there is relatively shallow and flat, so I would assume the detection would be relatively easy compared to AF447 hidden in a bunch of underwater mountains.

The searched for the pingers in the first 30 days right where they eventually found the debris, but did not detect them for some reason.

http://www.flightglobal.com/news/ar...acoustic-sweep-missed-af447-recorders-356286/
The acoustic search started on 10 June 2009 and covered around 22,000km² [6415nm²]. This amounted to 74% of the initial target area surrounding the last known position of the aircraft, and crucially included the place where AF447 was eventually found.
"When we compared [our search] to what we did in the past, we noticed we were searching this area before," says a spokeswoman for the BEA.

"The issue is to know whether the pingers stopped because they were out of order, due to the impact - we need to check that - or if we had not searched properly with the equipment."

She points out that wreck was found at 3,900m and the exploration marked the "first time we've searched at such a depth", and the BEA will assess whether the equipment deployed in the acoustic phase was adequate for the task.

While a nuclear submarine was enlisted to assist the search, its sonar interceptor was not originally designed to pick up the 37.5kHz beacon signal. Lower-frequency transmissions, around 8.5-9.5kHz, would have improved the chances, says the BEA. But improved sensor settings enabled the maximum distance for detection to increase from 2,000m to 3,200m during the last 10 days of the acoustic search.
