I don't know what altitude would cause a compression issue, but there is some altitude higher than 40,000 ft that would do it.

it could go higher, that altitude(43.1K actually,) is determined, among other things, on the ability for the crew to be able to get it from that altitude don to 14k in 4 minutes in the event of a rapid decompression of the cabin

Didn’t the German wings captain get locked out going to the head? frick, at least this guy had an inkling of compassion to depressurize and knock everyone out. The German wings captain and passengers had no doubt about what was happening at the end.

That would be an all time classic press conference by the Boeing CEO, if true.

quote:

Ladies and gentleman, I am pleased to announce on behalf of Boeing that the problems with our MAX airplanes have been fully solved. You and your families can be assured that you will be completely safe flying in one of our MAX aircraft.

However...it has come to my attention that our 777 aircraft have a small fault in the flight software where under certain extreme conditions, the aircraft may decide to fly itself into outer space.

Story gets interesting at section 5. Debunks a lot of theories while giving logic to why the pilot is the one who is most likely the culprit. Malaysia didn't want to be too helpful because they were afraid they would be seen incompetent. . . turns out that happened anyways. Interesting read. Got a little more to go, but I'm convinced the pilot went on a suicide mission.

Why would the pilot have a way to do this? For what reason?

Great read. Long as hell but it was good if you are interested in the subject.

I hear what you’re saying, but shite - it’s like if you got robbed, shot and carjacked.. but the thug left $5 in your wallet... i guess it shows a little compassion on the part of the pilot, but i cant for the life of me figure out why he wouldnt just take his own life some other way... then again, I’m not mentally ill.

A pilot friend once described a situation they call coffin corner to me.

Deflates the possibility of the pipe dream escape velocity. Also could be what the pilot did to his own plane, if he is the culprit?

Lifted from Quora:
For subsoninc jet aircraft flying in very thin air at high altitude, the speed required to keep the wings aerodynamic becomes faster and faster until it approaches the fastest speed the aircraft can fly at safely. Trying to climb higher, either purposely or by error at this point can cause the wings to lose lift. The resulting plunge speeds it further, approaching the maximum speed the air frame can tolerate. Any attempts to maneuver the plane at that speed can over stress the air frame and cause an inflight break-up.

The depressurization was done to reduce the oxygen in the passenger compartment. Basically to kill the passengers so they couldn’t interfere with his plans. The climb to 40k was just to speed the process up.

There are a few intermediate levels but pretty much any plane that is flying over 12500 for more than 30 minutes would require either oxygen or pressurization. If not, hypoxia and eventually death would occur.

The passenger area’s oxygen masks had 15 minutes of oxygen, the cabin has hours. Basically enough oxygen to get the plane down to a safe altitude. If he depressurization the plane, the masks probably popped out. At the higher altitude that 15 minutes for the passengers was down to just a few minutes.

The captain did it. Intentionally and manually. Shitty way to go, to take the passengers with you. Other than that, I’m sure the impact did him in instantly.

Is there not a protocol that if one of the pilots leaves the cockpit, a stewardess has to be in there? Seems like a bad idea to allow just one person alone?

It still blows my mind that we aren’t capable of tracking airlines no matter where they are. I understand there is some safety in that. But I’d think we could do some sort of 30 second delay ping of their location off of a satellite.

Eta: I’m not sure why this story is chilling, Pilot suicide was one of the very first theories.

Interestingly enough, the U2 spyplane flies in the coffin corner. On purpose.

There is more information than is necessary at the beginning but it certainly picked up steam.

The bottom line I'm reading is that there were really no signs the captain was going to do what he did. I do believe there were signs he was depressed to some degree but not quite to the point of homicide/suicide. It's unrealistic to expect officials would have access to the pilot's home computer to see the flight path he was rehearsing. Pilots get divorced frequently I would assume and depression of some degree would generally follow. What degree he displayed I doubt we'll ever know. Sounds like some friends knew that the captain was depressed but I imagine he was subtle enough in his actions to avoid detection. Although, Malaysia's public statement about him being very stable and happy in life is telling that perhaps they knew he was having personality conflicts.

The families being angry at the investigation is seemingly a misdirected form of mourning. No matter what the investigation shows, it won't bring their family back. We don't always get answers to questions in life. I am curious what Malaysia has changed about their air traffic control procedures. Based on reading the article, they don't seem to be very competent or willing to acknowledge any retrospection. I could see them maintaining status quo.

I'll throw something else out there. What if the plane never came back to ground but instead kept climbing, to the point it left earth's atmosphere? I know that a space shuttle has insane amounts of thrust/force/speed to get off the ground and into space, but could a plane, already traveling at 40,000 feet doing 500+mph pull the nose up and just keep going? What if that plane was so fricking high that it just left the gravitational pull of the earth???!?


Yeah like has anybody checked the moon, man?

Some excerpts. It really is a great article.

quote:

The cabin occupants would have become incapacitated within a couple of minutes, lost consciousness, and gently died without any choking or gasping for air. The scene would have been dimly lit by the emergency lights, with the dead belted into their seats, their faces nestled in the worthless oxygen masks dangling on tubes from the ceiling.

quote:

Which brings us back to the demise of MH370. It is easy to imagine Zaharie toward the end, strapped into an ultra-comfortable seat in the cockpit, inhabiting his cocoon in the glow of familiar instruments, knowing that there could be no return from what he had done, and feeling no need to hurry. He would long since have repressurized the airplane and warmed it to the right degree. There was the hum of the living machine, the beautiful abstractions on the flatscreen displays, the carefully considered backlighting of all the switches and circuit breakers. There was the gentle whoosh of the air rushing by. The cockpit is the deepest, most protective, most private sort of home.

quote:

Either way, somewhere along the seventh arc, after the engines failed from lack of fuel, the airplane entered a vicious spiral dive with descent rates that ultimately may have exceeded 15,000 feet a minute. We know from that descent rate, as well as from Blaine Gibson’s shattered debris, that the airplane disintegrated into confetti when it hit the water.

You’re right and poor analysis on my part. My assumption was that the passengers had no idea what was happening but it’s likely not the case. If the copilot was locked out and the masks were deployed, there was no hiding the issue from the passengers and crew. Nonetheless, I’ll take depressurization, passing out over flying into a mountain. The German wings pilot was a sick frick; those poor people went through hell.
