I think it is safe to say the IAF has sufficient coverage to pick up a T7

IAF scrambles Su-30MKI after spotting UFO near Amritsar border
Just for a weather balloon they scrambled Sukhois.. may be they are more vigilant on their western borders..

latest Press conf

Malaysian PM says seems the US NTSB, FAA and our own UK AAIB are working on the data too and concur

Don't know how to paste your post here.

If that's the case (Satellite com/data system still "pinging" satellite after ACARS/CPDLC/ADS-C turned off) then the authorities would know how long the 777 system was active for. Is this the case?

Last Satellite communication was seen at 8:11am Malaysian time (GMT+8)

Captain PB #3932.

That actually sounds possible. How would you explain the cut of the ACARS info though?

but the sea is 4000m deep where they are now searching

Last location reported to be somewhere on the red lines...(the 40 degree lines)

This looks more logical, but the lines appear to be angulation related stopping at 0...

The angle appears to be the angle from the ground to the satellite, so 0 the satellite would be at the horizon.

So these 40 degree arcs is what the PM was referring to? & of course they are not a track, it is just that the last received signal was on these arcs somewhere.

Would the 40 degrees be determined by received signal strength as suggested?

As a Professional Pilots forum, these fanciful posts are embarassing. Heists, gold bullion, conspiracies. If you haven't anything sensible to post may I request you desist or join a different forum for fictional creative writing. 200 pages of posts, mostly drivel. Thanks to those few who have the expertise to elaborate on the facts.

OrvilleW 15th Mar 2014 09:32

All BS to date.
 
Come on people - I haven't seen anything posted in this discussion that remotely resembles anything professional, from pilots or rumour. It's all guessing and what-ifs. Why not hold off until you really have something? What is MAS senior staff really thinking and doing? What are the Malaysian armed forces holding (if anything?). What detail is available from other sensors (US etc) throughout the area? Somebody out there knows some of that detail....but I haven't seen it from anyone to date in this thread.

The INMARSAT which must have been involved in the last hours of pinging communication must have been IOR which is geostationary above the equator at 64 degrees east. (This is the only INMARSAT which deals with ACARS comms which has coverage over the longitudes that the plane was in then).

As I have said before, there would be no triangulation, just (accurate) distance information gleaned from the time to negotiate a single ping (a few short messages backwards and forwards).

The announced northern corridor (N Thailand to Kaz/Tkm) tells us that the distance measured from the final (8:11am) pings was about 4550 km as measured on the earth's surface (to a spot below the satellite). That is how far those two ends of the corridor are from the spot.

So the possible 8:11am locations lie on a circle of that radius around that spot.

I will post a map shortly.

Interestingly, also on that circle, within the northern corridor is Hotan.

I have operated SIN LHR for the last few years routing over KL, Port Blair then over Calcutta. The new info about this flight being flown over this similar route makes we wonder if it "tailgated" such a flight heading towards India.
SQ068 was discussed earlier as such a possibility but nobody was ever able to confirm its routing on the evening in question. This is clearly not an amateur operation and that might be quite likely. Coupled with the US General stating that the flight's destination was Pakistan would also compute. Beyond Pakistan, they would start running into some very sophisticated US Military kit, both on the ground and in the air so Kazakhstan seems less likely?

That asssumes the NW track, which would logically be more likely in the case of piracy. IMHO, that is less likely than the SW track, more likely in the event of a suicide mission by a party or parties unknown and for unknown reasons. The US has already deployed assets to the IO and, I'm sure Submarines will already be lurking thereabouts also.

These new developments make the reports of pax mobile phones ringing much more plausible now.

Press conference #MH370 scheduled at 5.30pm today is cancelled.

No reason given on twitter

Live TV | Astro Awani - have reporter reporting from there in an empty conference room but in Malay.

Cargo Inventory
 
Some day we will get to hear what MAS believed was in the cargo manifest, it's perhaps too sensitive to release for now.
But given increased security/scanning over the years how easy is it still to load cargo described as "X" but actually contain "Y" ?

Military defence systems
 
What does all this mean in terms of military defence systems throughtout SouthEast Asia and further.? It looks as if I can load up with nukes and ramble around the skies to my hearts content till I find a nice place on which to drop them. No one will 'see' me with either ground radar, airborne radar or satellite imagery. I thought billions were spent on magic protective envelopes that no missile or aircraft could penetrate. So much for all those campaign ribbons on the military chests not to mention presidential pride of inviolable airspace.
I can't believe that 'they' don't know plenty and that we are not being lead down every garden path there is in order to cover up the reality.

In answer to Why would hijackers crash into the sea/go beyond fuel range you have to remember that these are desperate and highly motivated people to a degree which our idea of "logic" cannot comprehend.

Who says the hijackers crashed the plane into the ocean? One of the pilots might have done that when realising that all was lost. perhaps a pilot also repeatedly warned the hijackers that fuel was running out, but was ignored....this has happened before.

ekw 15th Mar 2014 09:43

A lot of people are jumping to conclusions with the word 'hijack'. It just means unauthorised excursion. The pilot flying is still in the frame. If it is murder suicide then where better to hide the evidence than in the deepest most uneven part of the Ocean. That would be SW of LKP.

Indeed, the total lack of information about those investigations is very suspicious.

I can't help but think there is indeed a secret mission in progress to what is becoming more and more likely to be the final location.

ana1936 15th Mar 2014 09:47

Thanks StormyNight 3965 for the post of satellite angle diagram.

The angle of altitude of satellite INMARSAT IOR (which is as I mentioned the only ACARS one covering this area) at 64 degrees East, as viewed from a place on Earth, which is what the lines show, can be calculated from the distance from observer (or pinger) to satellite.

This, in turn, can be calculated very precisely from the time taken to negotiate a single ping (which has some back and forwards messages).

So they have calculated such an angle of 40 degrees for the last ping.

Just an observation about the Prime Minister's statement after reading it twice.

The idiomatic structure suggests it was drafted or edited by a native English-speaker, and is not a translation of a Malaysian language original. And the idiom reads a bit more American, than British.

Given some of the phrasing, and the precise choice of words, very likely that NTSB and/or AAIB personnel in Malaysia (or elsewhere) were involved in writing the statement.

There are enough navies in those waters watching each other and using sophisticated technology to listen for trespassers that someone must have heard something.

Recent hints about a seismic event in the South China Sea are probably veiled hints as to where the 777 may have splashed. And if no one heard anything, then the governments don't want the other governments to know how really bad their surveillance nets are.

For all of that, we may have to wait 20 years for the wreckage to be accidentally found by oil prospectors... It is an ugly story of jihadis getting in over their heads (and losing control of the plane) and Maylaysia not wanting to admit that they failed to prevent it.

The sonar locators on the CVR and DFDR are extremely short range looks like the beancounters were involved again. They are fine if you have a known position down to half a mile or so in water, but their range is only a kilometer or so at best. One would have thought with whale 'song' being heard over hundreds of kilometers that engineers could have made these locators more powerful, but it possibly saved $100 per airframe to have pen torch sized locators with only 30 days power.
