Malaysia Airlines 777 missing

The US has a similar system, we used it to track airborne drug runners coming from South America and in the Caribbean and the Pacific. gave us cueing to pick up the aircraft with our own conventional radars.
There are apparently three stations, I knew about two - one in Texas and in Virginia didn't know about the one in Puerto Rico.

Under the ROTHR entry of the wikipage.

Mentioned this early on in the thread, way back... didn't know it was public information though, but I guess I never looked.

From BBC...




This was my question about the 14 min. It sounds like the ACARS message at 01:07 was routine and the next was due at 01:37. At 01:21 the transponder signal was lost. Is it just me or does this support the idea that the 14 min gap means nothing? Couldn't something catastrophic have happened at 01:21 that killed both systems?

Fire spreading in the avionics bay.

I haven't read the whole thread, but that image above is a different radar system, PAVE PAWS - that is more similar in nature to a conventional radar other than being a phased array radar than ROTHR which as mentioned uses HF energy.

So many things I assume are classified...

Better safe than sorry when it comes to a career though!
 
I read a conspiracy post involving TCAS, and want help understanding the system a little better.

This http://keithledgerwood.tumblr.com/post/79838944823/did-malaysian-airlines-370-disappear-using-sia68 alleges that MH370 slipped up underneath Barcelona-bound Singapore flight 68 (SIA68) and trailed it over the Stans before dropping off and landing, effectively masking its presence from interrogating ground radars.

The guy says this about MH370 using TCAS to find and intercept SIA68, but SIA68 not being able to detect MH370:

However that system only operates by receiving the transponder information from other planes and displaying it for the pilot. If MH370 was flying without the transponder, it would have been invisible to SIA68.

In addition, the TCAS system onboard MH370 would have enabled the pilot(s) to easily locate and approach SIA68 over the Straits of Malacca as they appeared to have done. The system would have shown them the flight’s direction of travel and the altitude it was traveling which would have enabled them to perfectly time an intercept right behind the other Boeing 777.


Aside from one B777 catching up to another B777 at cruise, does TCAS technology work this way?

Read a report yesterday on a mid air collision in Brazil and I quote: "While both planes were equipped with TCAS, it was later determined that the Embraer's ttransponder had ceased operating almost an hour earlier, at 16:02, rendering both planes unable to automatically detect each other." (source: http://en.wikipedia.org/wiki/Gol_Transportes_Aéreos_Flight_1907) - hope this helps
 
Cray Cray question. There is absolutely no way investigators know what time ACARS was taken off line right? All they know is it didn't check in for it's next scheduled update. So why do they keep saying ACARS went offline at a different time then transponder? How can they possibly speculate this. To me, it seems very plausible both systems went out at the same time. Thoughts?
 
I'm curious how hard would it be to sabotage the pressurization system? At 30,000 plus feet time of useful consciousness during a rapid decompression is measured in seconds. Practically the whole plane could be dispatched while keeping them in their seats (because of the oxygen masks).

Maybe the terrorists stole a whole airplane to use as a flying bomb

If he wanted to kill himself/crash they would've just nosed it over, why go to all that trouble. I'd bet it's on land somewhere, and intact.

I can't understand how people keep making this assumption. The rational thing would be to crash immediately, or use the aircraft as a weapon. But once you get to the point that you commit to hijacking a pax loaded 777, who says you have to play by or will play by rational convention or thought.

A single pilot hijack and flight until flame out is a very real possibility in my mind. I see absolutely no reason to discount this idea.

Certainly a good point. The only thing I would say doesn't fit your theory is the methodical disabling of the reporting systems.

Simultaneous loss of ACARS and transponder seems likely, but that's neither been proven nor disproven.

ACARS last checked in at _:__ (I've seen different times reported) and was supposed to check in again 30 minutes later. The transponder went off between the two times.

With the latest reports, we don't definitively know IF the ACARS and Transponder were turned off at separate times.

I thought it was PAVE PAWS (UHF) first as well, but upon closer inspection it's actually the USAF OTH-B system, with sites in Maine and California/Oregon. It was apparently put into cold storage after the fall of the Soviet union. The US Navy runs ROTHR.

Meh, wikipedia and google maps makes everyone a defense industry analyst. :)
 
It's been about 10 days and no-one has come forward claiming responsibility nor establishing motives with the flight crew. I think the longer this goes on, the more its looking like an accident.

An event of some kind breached the hull in the vicinity of the flight deck, injuring the pilots, depressurizing the aircraft and knocking out most of the avionics. The CA & FO were unable to immediately put on supplemental oxygen while fighting for control of the aircraft as it climbed to FL 450 and then descended to FL 250 (or whatever), before settling somewhere in the flight levels. If still alive, the CA & FO were unconscious. Other passengers would lose consciousness when their chemical oxygen generators ceased operation, or as they panicked and left their seats. Cabin crewmembers who grabbed portable oxygen bottles were also facing loss of consciousness as their supplies were exhausted. They may never have even attempted to access the flight deck physically, assuming that the pilots had regained (or were regaining) control. Calls on the interphone went unanswered.

The aircraft was now unpiloted and essentially NORDO, with the autopilot disengaged and power set wherever it happened to be. The heading was wherever the aircraft rolled out and "stabilized." It gradually climbed and descended with whatever stability is inherent in the B777 airframe at that power setting, along the southwesterly Inmarsat arc, beyond radar & radio contact, over open ocean, until fuel was exhausted.

Or it could be an alien abduction.
 
On one of the social media pages I follow, someone is crowing about "well, the Israelis think..."

So I asked "all of them? Really? From the Bar Rafeli sunbathing on the beach in Tel Aviv to the settler in a Kibbutz, they're all running up some conspiracy?" :)

I'm gojng to get banned.
