You would lose consciousness very quickly at 33,000 feet due to the incredibly low partial pressure of oxygen. So probably not many were conscious for long after the fuselage was destroyed.Politics, why's and how's aside...I just feel really heartbroken for the people who loved those on board the flight, and for those who have to go over there to investigate and recover the bits and pieces of the adults and children who were in it! I just hope whatever happened, that the suffering was over as quick as possible....I dread to think how terrified people were if they were even concious for a second when it all happened. So so sad :arghh:![]()
Unlikely that anyone would have been conscious after the aircraft broke up. There's not enough oxygen at 30,000 to sustain life so everyone would be out like a light pretty instantly. A few might have started to come round on the way down, but probably wouldn't have been sufficiently with it to work out what was happening.
There isn't enough oxygen @ 30,000ft to sustain human life for very long it's true. But "useful" consciousness, in test conditions, of around 2 minutes is common; and continued consciousness but with loss of cognitive functions of around 6 minutes is also common.
I would think though, that possible injury, or even sheer panic would result in very swift uncosciousness at that sort of altitude. Poor sods
An extremely rapid drop in oxygen partial pressure can knock someone out in seconds. Especially if it is preceded by or concomitant with rapid hyperventilation or increased heart rate.There isn't enough oxygen @ 30,000ft to sustain human life for very long it's true.

The time is between 1 minute and 30 seconds assuming you are at rest. BUT, it's reduced by 50% if a rapid decompression and reduced again if doing any form of exercise. While the pax were sat and theoretically at rest, the heart rate would go sky high as a break up happened, so equivalent to very hard exercise, meaning your heart wants much more oxygen that your lungs can deliver. At that point the brain goes to screensave. You'd be unlucky if that process was more than one or 2 seconds.
My source? One of the Pathologists after Lockabie.
Some people might start to come round on the way down, as they get to more oxygen rich air. But at terminal velocity, by the time the brain goes though start up, it would be that final 1/2 inch time, ie the bit that causes the damage.
Obviously a number of people would die instantly, if it was a SAM, they don't at many think, strike the aircraft, they explode nearby and 'pepper' the aircraft with shrapnel.

Fox News said:An Australian woman who lost her brother and sister-in-law when Malaysian Air flight 370 vanished in March is grieving again after discovering her step-daughter was on Malaysian Air flight 17 Thursday.
It is from Fox so I'm taking it with a pinch of salt. However if true, this is beyond bad luck.

Tragic really, however I was reading a story of someone who missed being on both flights, the world is full of weird coincidences...
Indeed. I imagine the person from your story is looking at life from a new perspective.
it's really just terribly tragic
Tragic news. What else can you expect while Putin is in power? I fear there is a lot worse to come

my understanding is that it roughly says it's outside the Embassies of the Netherlands in Kyiv and Moscow giving the numbers of deaths and a commentary on deducing who lives in a civilised world.
It's ineffectual nonsense which just serves to make people feel a part of something they are not a part of.

More relevantly, with all the hand wringing over Thurday's diabolical murders, and all the political posturing, we know exactly where the USS Vincennes fired exactly which missile to murder the passengers on Iran Air 655!
The Ukraine forces in the area are a little cut off so they've been using transport planes to resupply the troops. Thus the need for the rebels to have anti air. One rebel leader did broadcast that they'd captured a launcher, complete with serial numbers.
However, they aren't simple units to use and need skilled troops. It's well known that Russian special forces are assisting the rebels, it wouldn't surprise me if these have had minimal training in the use to provide assistance in its operation.
Slight difference in that the Vincennes issued several radio challenges and fired after that, however was in Iranian waters. Unlike the rebels, these were supposed to be highly trained operators with top equipment however thee were several errors made, attributed to inexperienced crew,
There is video footage around of a buk missile system being quickly moved out of the area
http://www.washingtonpost.com/news/...-shows-buk-missile-system-en-route-to-russia/
My info [ from people/friends in Ukraine ] is that the Buk is just one 'vehicle' and to make it operational [ badly explained] another two units are also needed - and the three parts are operated by a trained crew of between 12 and 15 operators.
Whilst this is true, you need some pretty specific training to be able to use it. There's no doubting it's ability, as they've shot down helicopters and a transport in the region in the last two weeks. The question has to be asked why the airlines weren't actively avoiding the area (apart from cost)
