Besides, the plane was reprogrammed to turn BEFORE the "good night". They would only do that if there was a problem, yet they failed to mention anything like that with the "good night".
Any cautious person will be prepared for an emergency.

Very true but the pilots of Helios 522 and the Payne Stewart plane were prepared for emergencies too, but castrophic events led to "zombie" planes full of dead people until both ran out of fuel and fell to the ground.

CNN has explained that. You have to be within about 2 miles (????) etc. to hear the ELT.

Of course, if it crash landed on land, then it would have also sent out the satellite signal, so the mystery continues... Must have been a soft landing either way.
The ELT would trigger upon impact with water, true. But then it would go down with the plane. Under water, the ELT radio signal is useless (radio waves are absorbed by water). The FDR and CVR emit a sonar pinger, which can be detected from a few miles away under water.

Wouldn't the Australians have been able to see the plane on radar?

Why isn't there a ship on the way that has helicopters on it? They keep talking about how long it takes to fly to the search site and back, and how it only gives them a small window of time for searching. If there were a ship on site, they could do a lot more looking.

I had no idea that the Aussies had such extensive radar. I suppose it's possible the plane managed to stay just west of it. I'd like to see a more definitive radar map superimposed over the possible flight of the plane. (They say the debris are 1,500 mi offshore - [here: -43.976111, 90.960278] - it's southwest of the southwestern tip of Australia). I'm guessing, though, that if the Aussies had caught it on radar they would have said so.

I think a big part of the problem in this whole thing is that various countries do not want to share their radar data or reveal any facts about radar capabilities. I am wondering why we have not heard a peep from Indonesia - 370 flew either right over it or very near it.

Oh my god! I just heard two CNN commentators playing an example of the "ping" given off by the plane to a satellite or other sensor. They were both shocked by the fact that it wasn't very loud. It was coming off a scope of some kind, together with the squiggle (highly technical term) shown on the scope with each ping. They commented on how such a low volume sound had to compete with the sounds of ocean animals and such; and even how the seagulls and other birds in the air making sounds would make it difficult to hear. I kid you not. Where do they find these people that don't understand that it is an electronic signal? Maybe just turn up the volume knob?

Add a little detail. "good night" was the expression in Homeland last season to signal take the bad guys out.

Doesn't jive.

People still see Elvis too.
I don't know, we are talking about a foreign country. We can't assume too much about how they operate.
