The radar onboard SIA68.

Why would a civilian jetliner carry it's own RADAR set? Beyond perhaps a forward-looking sort that picks up weather I mean. Which would be completely blind to a plane on the rear quarter. Why do you think military fighter and attack planes depend so heavily on AWACS with it's big bulging antenna to give them the full picture? Because the little unit packed in their nose can't see behind, so they are vulnerable there.

Mark my words, there'll be a flurry of aircraft modifications now as they are all secured with location transmitters which cannot be trivially disabled.

Weather as you mentioned, plus mountains in the clouds as I mentioned, plus instrument landings and collision avoidance.

Mark my words, there'll be a flurry of aircraft modifications now as they are all secured with location transmitters which cannot be trivially disabled.

Maybe so, but pilots are reportedly saying it's already "not easy." I don't know how much more difficult it could be made without interfering with the ability to shut down electrical systems in the event of a fire.

Or it only stayed in the shadow until it reached an area that was free of radar coverage, and then detached.

All this just to crash in the ocean? And once again, with all communication turned off, how would the pilot know he was in a dead zone?

If he wanted to go unnoticed by radar just to crash far away in the Indian ocean, he could have flown low :

Interesting interpretation here about MH370 shadowing another plane to get to the 'stans:

http://keithledgerwood.tumblr.com/post/79838944823/did-malaysian-airlines-370-disappear-using-sia68-sq68

I've seen this theory on airplane enthusiast sites (well before this guy wrote about it -- relative newcomer this guy), but it's pretty far fetched. For example, what about wake turbulence? Military planes do this sometimes, but only under certain conditions and with certain distances. It would be extremely difficult to do this for several hours, given the concentration required and it being nighttime, and the overall margins of getting it right. You could probably do it for a very short time, but not for the period stated. If you made too many mistakes, the blip might be too big, and they might scramble planes after you anyway.

For the conspiracy theorists, the other possible shadow flight suggested is KL 836.

I would add that the ascent to 45,000 feet over land could be for a couple of reasons:

1) To reduce chance of someone on the ground noticing an unidentified night flight

2) Pressure in the cabin would drop enough they'd almost certainly all be unconscious or near enough. Take a portable oxygen unit, and disable passengers. Tie them up, drug them, kill them.

This is nonsense too. For 1) it would make more sense to fly at 5000 feet instead of 45,000 feet if you want to evade radar. For 2), the spec on a 777 is 43,000 feet, which likely includes a margin of safety. Do you really think 45,000 would incapacitate people on the plane? I doubt depressurization would be a problem at that altitude, and more mundane concerns like thrust and stall would come into play (i.e. that the airplane might not be able to achieve or maintain that altitude at close to full load -- remember that this is a big loaded plane).

The maximum altitude certification of a plane is also at least partially based on the ability to get to 14,000 feet. The plane must be capable of getting to 14,000 feet within a certain time period in the event of a cabin depressurization, according to legal requirements. It's not that the plane isn't capable of going higher than the certification, but rather that there are other concerns -- all of the above.

And before anyone says something about landing on a 3000 foot unreinforced runway, sure, you could, if you left zero safety margin, used maximum braking, and landed right at the threshold, especially if you weren't heavy loaded and are okay risking your airframe. The runway might also give way if you did that, so you'd probably only do it in an extreme emergency, and I'm not sure how you'd take off again with that short a runway.

One pilot suggests accident theories consistent with the reported altitude changes.

Shadowing SIA68 would not be consistent with the reported altitude changes, unless that plane also climbed and descended at odd times and for no reported reason.

Also, any altitude above 40,000 feet would probably be fatal if the cabin was not pressurized. That's why I suspect the plane climbed to its maximum altitude, i.e. to neutralize the passengers.

A great failing we realized after 9/11 was all our NORAD radars faced outwards, so we couldn't even locate fucking domestic airliners inside our borders

I think that was done to keep the older radar systems from interfering with TV and radios signals.

44171 corntrollio 2014 Mar 17, 8:45am

One pilot suggests accident theories consistent with the reported altitude changes.

Those altitude changes must be bogus anyway because they don't meet any reasonable specs -- here is a link from the NYT article linked within that CNN article (http://www.nytimes.com/2014/03/15/world/asia/malaysia-military-radar.html):

Investigators have also examined data transmitted from the planeâ€™s Rolls-Royce engines that showed it descended 40,000 feet in the span of a minute

I think the data that was allegedly released is made up. There's no way it descended that quickly -- even if it was half that rate.

The problem here is that we have no way of knowing whether the reports have been accurate or not, especially because the Malaysians have been inconsistent on occasion. Either they're incompetent, they're hiding something, or they're trying to protect their government airline at the expense of a good investigation. That's how all this "the pilot supported the opposition government" nonsense strikes me.

Also, any altitude above 40,000 feet would probably be fatal if the cabin was not pressurized. That's why I suspect the plane climbed to its maximum altitude, i.e. to neutralize the passengers.

How would the cabin not be pressurized? The 777 pressurizes the cabin to about 8000 feet. Also, 45,000 isn't the maximum altitude in the spec for the 777 -- the max altitude was 43,000, or 43,100 to be specific (FL 431 in aviation-speak). The spec for a 747 is higher, more like 45,100 (FL 451). I've flown at 41,000 feet in a commercial airliner, but I believe the regs require at least either the pilot or first officer to wear an oxygen mask at above FL 410, so they don't usually fly higher unless there's a reason. I suspect that 747s may fly at FL 450 when the conditions warrant and they are flying empty, but otherwise, it's probably very rare.

Update: Cite for the 41,000 feet threshold for an oxygen mask:

More so to keep the fighters stealthy. Its kind of silly to spend a billion dollars to make a stealthy fighter only to light it up with the equivalent of a "kick me" sign.

Why would a civilian jetliner carry it's own RADAR set?

All airliners have weather radar. It would show other planes, but only forward since the antennae faces forward. It has limited range so finding another airliner would require very precies information on tracks and times. Snuggling up close enough for military radar to register one return would be very difficult. Keeping it up for hours would be even more so.

or 2), the spec on a 777 is 43,000 feet, which likely includes a margin of safety. Do you really think 45,000 would incapacitate people on the plane? I doubt depressurization would be a problem at that altitude, and more mundane concerns like thrust and stall would come into play (i.e. that the airplane might not be able to achieve or maintain that altitude at close to full load).

Airliners start cruise at 30,000 feet or so and gain altitude as they burn off fuel No way no how a 777 could get anywhere near 43,000 feet unless it had burned off most of the fuel. The other problem is speeds and elevations are very carefully calculated to avoid stalls. An airliner works very close to the edge of stall at cruise speeds and altiitudes. Aerodynamic stall speed gradually decreases with altitude, supersonic shock stalls speed decrease with altitude. At some point they overlap and the plane stalls. This is called coffin corner. Not at all a good thing with a 500,000 pound plane flying 500 miles an hour. A pilot randomly setting speeds and altitudes would be playing a very dicey game. Flying at 5000 feet would guzzle fuel at a huge rate, jets are only efficient at high altitudes. Pressurization wouldn't be any problem at all. Concords flew at 55,000 feet every trip.

curious2 2014 Mar 17, 9:09am

How would the cabin not be pressurized?

Either by accident or on purpose (i.e. if whoever disabled the communications next disabled the cabin pressure). If either unattended or piloted by someone suicidal, the plane might reach a maximum altitude somewhat out of spec, which might explain the reported 45,000 feet.

Okay, so I'm going to humor you here. If that's really the case, and you're already at 35,000 feet, why do you need to rise to 45,000 feet? I'm pretty sure people would be unconscious in less than a minute at 35,000 feet already, so why do you need to risk the airframe to go higher?

Again, I'd also point out that these numbers make no sense. There's no way in hell the pilot or first officer descended 40,000 feet/minute. That's 454 miles/hour downward, for one thing. Second, you would probably be going past Mach 1 when you got there, which means not good things. Third, you would have to be very skilled to take yourself out of the dive without ripping wings off or having G-forces rip something else on your plane. You can do some crazy shit in a 777, but they aren't designed for things fighter pilots might be able to do.

Agree, I'm familiar with the coffin corner concept.

Agree on all accounts. Flying at 5000 feet would guzzle fuel a lot faster and you couldn't fly the full 5-7 hours or whatever these guys allegedly flew, but it would evade radar. It would be far simpler to do this, to evade detection, than to shadow another 777 for several hours.

Concorde was designed for those high elevations more so than a 777 -- I believe there were additional systems in place for higher altitude, e.g. the smaller windows plus additional air systems in case there was a cabin breach. I believe Concorde also pressurized lower -- more like 6000 feet, but I'd have to check to be sure. I believe the new 787/Dreamliner also pressurizes around 6000 feet. Concorde also was still required to meet the emergency descent requirements I referred to above.

Another thing I am wondering about. If the plane had exploded ala TWA 800 would early warning satellites have picked up the heat as a potential launch? If the plane crashed mid ocean might the sound of such a crash be detectable by SOSUS? I think the US has at least a small SOSUS by Diego Garcia. After the big quake of 2004 there was also talk of installing a more complete microphone network in the Indian ocean to better detect underwater earthquakes. If it was ever installed such a system might also be able to indicate where an airliner like this one went down.

44178 corntrollio 2014 Mar 17, 9:25am

You added this text afterward.

How would the plane go to 45,000 feet unattended?

Also, why wouldn't a suicidal pilot just crash the plane into the ground/ocean at the first chance possible (again, Occam's Razor fail to suggest that they would fly around for several hours first).

On one site, some people were obsessed with the (im)possibility that the flight was going to Somalia. Why? Because there are pirates there? Mogadishu is too far, for one thing, but you'd also be crossing over Indian mainland territory if you went from somewhere near Port Blair (IXZ, where apparently the radar was off) to Mogadishu (MGQ).

Those are the reported altitudes. If I had to guess why climb above normal cruising altitude, maybe it was to depressurize faster and create an upward pitch preventing anyone from rolling a drink cart through the cockpit door. Or, as one pilot wrote, it might be a damaged plane with no one controlling it. Either way, you aren't humoring me and I don't find the loss of a plane with 239 people particularly amusing. Neither of us was on the plane, so we don't know exactly what it did, let alone what it could have done. I would guess though that if the pilot was committing suicide by plane crash then he probably didn't have the normal level of concern for the airframe.

To conceal the suicide, which must be concealed in order to collect on life insurance and avoid blame.

44181 corntrollio 2014 Mar 17, 9:39am

No, those are rumored numbers from an unconfirmed source. The rest of your argument depends on a shitty CNN article that makes a lot of random conjectures based on this rumored data that can't be confirmed.

To conceal the suicide, which must be concealed in order to collect on life insurance and avoid blame.

Well, the pilot was separated or divorced already, so I'm not sure why he would want his wife/ex-wife to collect. He did have a few kids already, so maybe he would want them to collect. I'm not sure about the heirs of the first officer.

Again, this seems far-fetched and convenient. This is not usually how suicidal people think. The movies have really shaped a lot of people's views on suicide in a way that doesn't really comport well with reality, at least according to studies that have been done.

In addition, you're assuming that the *intentional* action of disabling the transponder and other electronic systems would somehow escape the insurance company's investigation team? And then flying in the wrong direction incompetently would somehow cause it to be an "accident"? No insurance company would pay the life insurance claim until they had a lot more answers, and you're not answering any questions that need to be answered by this simplistic not well-thought-out explanation.

I don't find the loss of a plane with 239 people particularly amusing.

Nice attempt to appeal to emotion, but it doesn't make your tinfoil-hat theories any more plausible. This is going on all over the place -- there are even people trying to suggest the flight landed on Diego Garcia. Do they know what's on Diego Garcia?

"There is an axiom in Malaysian politics: Eventually everything comes back to Anwar Ibrahim. So, the longer that the fumbling and inept investigation into the missing Malaysia Airlines Flight 370 has gone on, the more certain it became that it would somehow boomerang to the leader of the countryâ€™s democratic opposition."

OK, I'm through with you. The reported numbers aren't my "argument" or "tinfoil-hat theories;" if you don't believe them you can go harangue the networks and investigators and pilots who have published subject to fact-checking. On my screen, you're just an anonymous commenter, maybe a 12yo in mom's basement, which is beginning to seem more likely, in fact if I must choose a theory I'll go with that. I've made few if any assumptions, being very careful to consider alternatives published by experienced authors working under their own names. Go harangue them if you must.

44184 corntrollio 2014 Mar 17, 10:23am

if you don't believe them you can go harangue the networks and investigators and pilots who have published subject to fact-checking

Again, your main "evidence" is a CNN article based on one non-Boeing pilot's musings based on unconfirmed data. Hard to call it solid. Even your source says the data doesn't make sense, although not directly:

Though these oscillations are larger than I might expect, it would be a natural behavior for the airplane to fly relatively large but gentle pitch oscillations.

Large gentle pitch oscillations are inconsistent with the alleged data that it dropped quickly. What he's saying is that an unattended plane could make *gentle* changes of those altitudes, but not sudden ones, as the alleged data claims.

If you really think that CNN article is "fact-checked," I don't know what to tell you. There are a lot of random theories being thrown around in a lot of news stories that have been "fact-checked" and I bet there are even more in the shitty cable-news broadcasts by completely uninformed people.

As I stated earlier, you could already depressurize people plenty at 35,000 feet, and in about a minute probably. Do you need the additional 45 seconds that 45,000 feet might get you to ensure people are unconscious? If the cockpit doors are bolted as tightly as people say, I'm not sure why you would. In any case, oxygen masks would come down, and the oxygen would flow for at least 15-20 mins or maybe as much as 30 mins. Why would you come right back down to 23,000 feet then and so suddenly?
