Interested to know more about the 5 fail to boards. They mustn't have come from a connecting flight as reports say their baggage had to be off loaded, so I assume they checked in at KL as I cant imagine the bags getting there before the pax.

avherald added this information recently;

Hong Kong's Air Traffic Control Center reported on Mar 10th 2014 around 17:30L (09:30Z) that an airliner enroute on airway L642 reported via HF radio that they saw a large field of debris at position N9.72 E107.42 about 80nm southeast of Ho Chi Minh City, about 50nm off the south-eastern coast of Vietnam in the South China Sea and about 281nm northeast of the last known radar position. Ships have been dispatched to the reported debris field.

Thomas,

Pingers only transmit on a limited range.

Once the aircraft is found the pingers are then used to locate the boxes.

Unfortunately it's a small fish in a big ocean until some trace is found.

Please excuse my ignorance, but of the theories that one of the reasons debris may not have (yet) been found is due to disintegration in the air caused by catastrophic explosion, I have these questions:

1. What would cause an explosion so powerful that complete disintegration would occur and leave no debris, even small parts of the plane flung far and wide?
2. Why would such an explosion at night not be seen by those on the ground or other intra-Asia redeye flights flying at similar altitude on a clear night?
3. Etc.

With respect, Ash - your answer was not accurate. If a transponder is switched off (or fails) then in 100% of cases the aircraft data label will definitely be lost on the controller's display. Modern ATC radar centres do not display primary paints on controller's displays, either because that data is not available, or to display it would clutter their displays (or both).

Sure, the world's military would maintain some level of primary-only radar coverage for identifying unidentified intruders, but that's not we're discussing here.

The whole reason primary radar is all but redundant is that there are so many limitations with it, as I explained in my previous post.

I thought my original answer was reasonably simple :) To make a blanket statement that the aircraft would still be showing on radar is generally incorrect in a modern civil ATC environment. That's why contact was lost in the first place :) Rescue services would have a more precise estimate of where the aircraft is, if your original statement were accurate.

With respect my answer was to post 59. Laurent was asking if it were possible to turn the transponder off and then fly somewhere else undetected.

Again whilst what you say is indeed 100% correct, my response, is also right, especially the context of the post I was replying to.

Now I am sure you will agree if an aircraft were have done was Laurent was suggesting then somewhere along the line it would be detected by radar and being unidentified suspicions would be aroused. Sadly other than a crash there is no way for an airliner to just disappear like it has done.

So the answer to Laurent again is yes an aircraft with a transponder turned off will still be detected by radar, but add all of Hugh's caveats.

On another note they are sending ships to the debris field spotted by a Cathay crew, crikey 250nm from the last position...

You too can help look for the missing aircraft....

An American company has set up a web site to enable users to scour the area where MH370 is believed to have gone down using imagery from 5 satellites. Web site below:

That's awesome. I'm already checking the first images.
