Has anyone mentioned the possibility of an offline jumpseater (pilot) and perhaps more than one jumpseater?
I searched the threads and found no reference.

As you perhaps know, there was some offline jumpseat involvement in the planning for the 9-11 attacks.

Apparently these modern aircraft have a "secret" compartment underfloor that even pilots are unaware of......if so, why ?
There are no "secret" compartments.
There are access panels to? ...... yes access the internals of the aircraft for maintenance.

Pings and arcs
ana1936 said:
In today’s (Sunday) press conference, the DCA Director also referred to calculations of the aircraft’s minimum and maximum speeds from last point of contact as considerations in determining the arcs.
bits of the circle can be ruled out by using other reasoning, e.g. lack of ping receipt by other satellites and time of flight
ana1936,
Thanks, sir. Then is it fair to say the plane could have been "holding" for hours at any point on the arcs as well as traveling in a track that could be describing those tracks?

If so, is it feasible MH370 was 'rebirthed' while out of civil radar range and entered new airspace as a different aircraft?

Understood. The "look angle" might also come into play. IE if the aircraft was flying north along the red line, but was banked left wing low the fuselage might shroud the antenna from the POR satellite with it that low in the sky.

multiple pings
cockpitvisit
"From the 6 pings, there must be 6 different rings. But we are only shown curves from a single ring (probably from the final one). Is there any information about the other 5 pings? It would at least help determine the lateral motion of the plane (how much it moved "towards" or "away" from the satellite)"
Maybe somebody has explained this already but you are absolutely right - we have to assume 'they' only had the transit time for that single last ping - if not there would seemingly be a treasure trove of further information from the other pings. However I think we can rely on 'them' to have extracted every last scrap of useful data.

@D.S.
ADS-C can send route data either on a periodic basis or if changed:
Predicted Route Group
If so equipped and engaged the a/c could send this data w/o pilot knowledge. ADS-C update with info listed above would be sent from plane to ground automatically when the pilot changed the next or next +1 WPT.
I'm not saying this is what happened. Just saying that what has been reported is possible.

There is no suggestion that the aircraft moved "around the arcs" - the arcs represent a set of positions where the aircraft may have been on the last hour's ping transmission.
I would be really interested to know the arcs where the aircraft may have been on each of the proceeding hours' ping transmissions.

To those asking about the ELKA ATHINA story, reported in various media as "the Elka Athina has reportedly picked up suitcases from the Malacca Straits" - the media have once again done a superb job of distortion.
The ELKA ATHINA was directed to keep an eye open, for possible wreckage that could include items such as suitcases, by the Indonesians. It was requested to do so as part of the SAR efforts in the Malacca Straits.
No report has come in from the ELKA ATHINA as to any wreckage sighting, so we can presume at this point, the crew of the ELKA ATHINA have seen nothing.
Back to the smoking holes 30' in diameter, the tinfoil hats, the crystal balls and the aliens ....

Are the a/c flying visible on the pictures? On the pic from the link above, on the "submap" 637975 (it is the fifth rectangle from the right edge, and the twentyfourth from the bottom), there is an "intact" a/c, even visible as a very small white point on the thumbnail map). And I don't see its shadow, but there is a black "band" on the pic, just west of the a/c.
From the api vs chalenge link, it this one : "id":637524,"overlay_id":1272,"lat":11.603921,"lon":92.77524 7,"status":1,"msg":"Retrieved map ID = 637524"

Australian PM just announced that he received a request from Malaysian PM a short time ago for Australia to take command of the search of the "Southern vector".
Oz PM says the Australian Government will "do its duty" toward those in the "ill fated flight".
More Oz maritime resources were offered and accepted today.
After the PM's statement, the opposition leader offered condolences to the families, extraordinary and rather direct message to announce in public unless you know that all the families have given up hope....

Radar Tutorial
This site Radar Basics
Provides an excellent in-depth explanation of current radar technology, especially the capabilities and operational characteristics of primary radar and secondary radar.
Many of the questions asked on this thread are answered quite clearly and simply on the site.
The link is to secondary radar entry, but the site covers a lot more.

My understanding is that the investigation team has the (distance/angle) data from all six(?) pings but has only publicly released the last one.
However, apparently CNN started reporting a few hours ago that the second last ping was from approximately the same angle as the last one. But they (I think mistakenly) thought that that meant the plane had stopped and apparently they have gone silent on this since then.
To repeat, all we know is that at 8:11am the plane was on (or crossing) one of the red arcs.
The public know nothing about where is was before that. The experts will know a bit more from the previous pings.
And not even the experts know where it was after 8:11am.
Except we can guess that something happened to the plane before about 9:11am.
