Unless they do it through satellite, I'm thinking it's a lottery... Like who's Orion draws the right search grid on the day.

Yep, true to a large extent. My reasoning is the Yanks seem to know something, since they have headed off by themselves (others may be following suit now) to the Indian Ocean with a ship and high tech aircraft.

OK - if the yanks do know something, then it's probably from some surveillance system they don't want to talk about.
With the possibility that it flew for 4 hours after the transponder signal was lost, there are millions of square miles to search - so much that unless it can be narrowed down, it's almost pointless trying.

Very likely they have some super secret information or they are following up on the "ping" info. I read on another site of an aircraft search in the continental US where the searchers had come up with nothing until the Airforce liaison officer discretely suggested looking in the opposite direction, bingo!!! object of the search was promptly located.

Even with the "ping" info I strongly suspect they have more than just a few "pings" to go on, there's been more than just pings transmitted.

For sure there's a large area to search. Logically that area can be reduced somewhat, It's most likely the aircraft flew in a straight line so you would start looking at the point of calculated range after the four or so hours that you have the pings for. I suspect they have an idea of which direction to look as well.

Boeing don't just make aircraft they are major players in the industrial military complex, so they will very likely have some systems we are not to privy to, whether relevant or not I don't know. If the plane did fly on for another 4 hours why did it not fly low over land so passengers could use their cellphones, can a foreign mobile make a 111 call in a foreign country ? ( at low altitudes)

I found this quite interesting.

Another wrinkle: In a CNN appearance on Thursday, the former National Transportation Safety Board vice-chairman Bob Frances called the WSJ story “remarkable”. In an interview with the Washington Post, he said:

“Andy Pasztor is a very reputable journalist who knows his stuff in aviation as much as anyone. For him to create this article out of whole cloth for me stretches credulity … So you don’t know where to go. I would go with what Andy said because I have great faith in him and he doesn’t have any political axe to grind, as do the Malaysians.”

Why would it fly low so as the passengers could make a phone call? I don't follow your reasoning.

My gut says there was an dramatic event that caused the crew to become incapacitated (and also the passengers) the aircraft was turned around prior to the crew losing consciousness and the aircraft flew on till it ran out of fuel or slowly descended into the sea or terrain.

to follow your reasoning the crew would not expect to be incapacitated otherwise they will mayday and land in the sea.

if they turned around they would make contact and only expect a minor problem.

Yep , so that suggests that everyone on the plane was either physically incapable of making such a phone call, was forced not to or a phone call / txt was technically not possible,
but according to the US ,they did fly over land, with cellphone coverage.

see opensignal.com

The US believes the flight took the following path.

and this reuters article http://www.reuters.com/article/2014/03/14/us-malaysiaairlines-flight-idUSBREA2701720140314 states that
"That course - headed into the Andaman Sea and towards the Bay of Bengal in the Indian Ocean - could only have been set deliberately, either by flying the Boeing 777-200ER jet manually or by programming the auto-pilot."

Meanwhile in China

http://seis.ustc.edu.cn/News/201403/t20140314_191123.html

The above when translated suggests there was a detectable "non seismic event" in the sea an hour after the 1.07AM disappearance.

where did they get these "waypoints"?

I don't understand what you're getting at here. Perhaps I didn't explain my theory clearly enough.

What if there was an oxygen bottle failure like Qantas had a few years back in one of their 747's?

There would be a fairly rapid depressurisation

There would be no oxygen for the crew.

Due to to the location of the O2 bottles in the 777, the avionics bay bay would likely incur some damage.

The mantra for any emergency is Aviate, Navigate, Communicate.

The crew would Aviate - ensure the aircraft continues to fly and ensure their own ability to stay in control (put oxygen masks on)

They would Navigate - ensure they were clear of terrain and get the aircraft flying where they need to go. In this case they would very likely consider a return to the departure point as the best option.

Communicate - Declare a Mayday.

The time of useful consciousness at 35,000' is 30 to 60 seconds. Research shows that with rapid depressurisation this time reduces significantly.

There isn't much time for the crew to do anything. The time of useful consciousness gets used up pretty quickly, possibly before there is time to make a mayday call - assuming those radios were still working.

So it is entirely possible the crew had time to turn the aircraft around using the autopilot and initiate a descent to 29,000' before they became incapacitated.

There have been questions as to why some equipment appeared to fail or be switched off at varying time times. In the case of depressurisation the cooling air being blown through the avionics isn't dense enough to do it's job properly and the equipment over heats and gradually fails.

if they knew there was a decompression they should

1) take a big breath and hold for as long as possible WHILE

2) descend to useful altitude ie 10000ft where your body would still have reasonable oxygen saturation (around 86%) from the partial pressure of oxygen at that altitude. (cabin is normally pressurised to around 7000-8000ft eq)

3) do the other stuff you mentioned

don't you reckon?

If you did that during rapid decompression your lungs would expand and rupture - not a nice way to go.
