South Dakota Learjet crash, the loss of a Champion - N47BA

Ғылым және технология

On October 25, 1999, a chartered Learjet 35 business jet was scheduled to fly from Orlando, Florida, United States to Dallas, Texas, United States. Early in the flight, the aircraft, which was climbing to its assigned altitude on autopilot, lost cabin pressure, and all six on board were incapacitated by hypoxia, a lack of oxygen in the brain and body. The aircraft continued climbing past its assigned altitude, then failed to make the westward turn toward Dallas over North Florida and continued on its northwestern course, flying over the southern and midwestern United States for almost four hours and 1,500 miles (2,400 km). The plane ran out of fuel over South Dakota and crashed into a field near Aberdeen after an uncontrolled descent.
The four passengers on board were PGA golfer Payne Stewart; his agent, and former Alabama football QB, Robert Fraley; president of the agency, Van Ardan; and Bruce Borland, a golf architect with the Jack Nicklaus golf course design company.

It was by far the worst serial number mechanically that I had ever flown. It even had a “nickname” - 47 Barely Airworthy. 😢 Let’s just say there is a little more to this story, but even I have some questions. GODSPEED!

    The role of the interceptors was to try and communicate with the crew of the Lear and then shoot the plane down if it appeared to to heading towards a populated area. Fortunately it did not. 911 happened very quickly for scrambling interceptors. But I do believe they were heading towards the UA 93 in Pennsylvania once it became obvious what was happening.

    @@erich930 I have not flown the Lear 35 , but most Cabin Altitude warnings occur at 13,500’. There should have been another major clue that the cabin wasn’t being pressurized. The one bleed air valve was found in the “closed” or off position after the impact. It most likely was never on. And the crew should have known that by the pressure change in their head as the plane climbed. Or by the yellow annunciator light indicating the bleed air valve was closed. The supplemental oxygen valve needed to be turned on from the outside of the airplane during the preflight. It never was. Even if they put their masks on there was no oxygen flowing to them. There’s more to this story that we will never know or be released.

    The narrator is correct that the percentage of oxygen stays the same but that the atmospheric pressure drops. So the percentage of O2 stays the same but there isn't enough of it to keep of alive. Another way of explaining that you need supplemental oxygen is that as pressure drops your body "out gasses" and eventually above 50,000 feet not even an oxygen mask can supply you with enough oxygen. Above 50,000 feet you need a pressure suit. At higher altitudes you can actually feel all the gasses trying to get out of your body. Belching and so forth. You can have so much pressure coming out of your oxygen mask that the mask actually pushes off of your face. At those pressures the challenge is not breathing in.....it's breathing OUT. The pressure being supplied by your demand regulator will inflate your lungs.....you have to concentrate on breathing out. At least that's the way it was at 41,000 feet in the Air Force altitude chamber.

    Basically, there isn’t enough room in your lungs for the amount of oxygen you need. The same principle is why the oxygen masks on Concorde would have been utterly useless if it had depressurised in supersonic flight. 60k feet is precious near the height where blood “boils” (it actually evaporates). You’d need a space suit or be breathing under pressure to survive, which you explained perfectly.

    Just curious about the valve failure. Most valves are designed to fail to the position of least concern, in this case I would think the valve would fail open which would not allow depressurization, ie having the valve closed with current or pressure by which if there is electrical failure or hydraulic failure the valve will open. Any thoughts on this?

Like the narrator said there IS a cabin altitude warning.....so it is extremely frustrating as to why the pilots didn't don their oxygen masks right away. The Captain was former Air Force so had had very good training in the altitude chamber.....he should have been well aware of his own hypoxia symptoms and well aware of what to do in case of a cabin pressure issue. But like they said, they can't know for sure what happened. Maybe the loss of cabin pressure was sudden and made everyone pass out before they could help themselves.

    This was an excellent explanation of the how hypoxia affects respiratory physiology, it is also worth including that in addition to what was so superbly explained, as altitude continues to increase so too does the available space, the ratio of gases remain unchanged but the distance between the gas molecules becomes greater as they diffuse into increasingly available less atmospherically pressurised space. The most visually useful analogy is that of a water spray bottle/atomiser, which we'll arbitrarily say contains 10mL of water. Transferring the liquid into another vessel is as simple as pouring it in, just as a syringe could drawn up any desired volume by placing the tip in the fluid and drawing back the plunger. If at once the entire 10mL contents have been sprayed, or atomised, forming a cloud comprised of micro-droplets of water, the suspended 'cloud' will now cover a larger area than the size of the original container. There is still the same volume of water or water molecules, they are just much further apart forming a vapour. Attempting now to fill the vessel, or place the syringe into the cloud of water vapour and draw back the plunger, will at best dampen the vessel or syringe barrel with a minimal volume of droplets due to how widely spaced the droplets of water are vs the former density of the contained water. Although the syringe's barrel creates a negative pressure as the plunger is withdrawn, it is still ineffective with capturing but a few water droplets. The same principle applies when trying to breathe at significantly higher altitudes, the same volume and ratio of gases exist, but when a lung full of air is inhaled, just as the syringe is ineffectively able to capture many water droplets so too is there an inadequate volume of gas molecules available to be captured per breath when the altitude is too high with the atmospheric pressure too low and the gas molecules that far apart. Also at such an altitude the significantly decreased atmospheric pressure negatively affects the efficiency of gas exchange. When the reduced volume of oxygen molecules inhaled per breath reach the air sacs better known as alveoli or the alveolar space, they also lack the force or pressure required to transfer across the membrane that is only one cell thick from the inside of the alveoli to the inside of the capillary, a micro blood vessel. Should the water droplets begin to coalesce forming larger droplets, the larger droplets then further coalesce forming even larger droplets and so on, it will become easier to capture more water in the vessel or syringe just as decreasing altitude with the atmospheric pressure increasing also coalesces the gas molecules to become more densely packed together, allowing a greater volume of oxygen molecules to be inhaled down into the alveoli per breath. As atmospheric pressure increases to a life sustaining level, the concentrated volume of oxygen molecules now have the necessary pressure for each molecule to be forced through the alveoli's single cell membrane into the bloodstream, once there each oxygen molecule can attach to the haemoglobin on the next passing red blood cell and be transported to where it is required. In a gradual depressurisation as experienced by the occupants of the featured LearJet or the occupants of the Helios Airlines B737 in Greece, the physiological response is subtle. The most noticeable and profound symptoms are the consequence of the oxygen-hungry brain being starved. There is a feeling of growing sense of fatigue, tiredness or light headedness as the body begins compensating for the reduction in circulating oxygen. This is followed by increasing feelings of euphoria and well being similar to having consumed a few glasses of champagne or other carbonated alcoholic beverage of a similar strength. The increasing sense of wellbeing and growing sleepiness eventually results in a loss of consciousness without the least sense of concern, worry or anxiety. There in lies the insidious nature of gradual hypoxia, it creeps up without warning or concern, by the time it is becoming life-threatening the affected person doesn’t realise nor do they care. Conversely in a sudden or explosive depressurisation, the symptoms of breathlessness are immediate, in addition to all of the other physical effects associated with the rapid expansion between gas molecules. Pain is felt in any hollow cavity containing trapped gases such as the ears, sinuses, stomach or at any length of the bowel, also dental pathology such as cavities or loose fillings. There will also be environmental signs such as extreme cold, a very loud noise coming from the breech in the fuselage's integrity, also the rapid drop in temperature will rapidly condense all the humidity into a dense fog** which dissipates after a short while. Any carbonated drinks will spontaneously fizz dramatically along with hot fluids suddenly beginning to boil violently. Both of which will overflow out of their respective containers. All dust and debris embedded in the carpet and flooring will instantly become airborne being forced towards to breech, as Will any loose papers, and small items. As soon as the pressure inside equalises with the pressure outside everything will settle down with the exception of the extremely cold air and noise. ** It is because of this temporary 'fog' or condensation that the masks that drop from the service unit above are a yellow/orange colour vs the typical transparent design of a medical oxygen mask. It is easier to see, grab onto, pull down and place over the nose and mouth. Incidentally, you may have heard of people saying cabin contents are 'sucked' out of the aircraft, they are NOT, just as overflowing sofa is is not sucked out of a shaken bottle. Cabin contents are blown out of the breech, the larger the breech the heavier and larger the items will become airborne and be blown through the breech with incredible force, always keep your seat belt fastened! The larger the breech will also dictate how quickly everything equalises and settles down. Having said that the faster the pressure equalises the greater the pain and discomfort from trapped gases and the onset from the dizzying effects of hypoxia. The Time of 'Useful Consciousness' (TUC) vs just the 'Time of Consciousness' is for those in aviation to be aware of the narrow time frame available, if an individual is not breathing supplemental oxygen within the altitude-dictated time, they will become overwhelmed and unable to make any sensible or meaningful decisions despite them still being conscious for the short term. The TUC at the altitudes most pressurised commercial aircraft fly, between 35,000 - 43,000 feet the time is roughly 30 seconds or less depending upon the health and fitness of the individual. In the case of a passenger affected by poor health or fitness (particularly respiratory disease/infection or cardiac issues) or if they are dehydrated or under the effects of any intoxicant, the TUC is significantly shorter. Flight Crew have specially designed quick fitting oxygen masks that also contain a microphone for continued unobstructed communication with air traffic control, the oxygen flows under pressure and at a higher concentration (including 100% if necessary) to maintain full mental capacity for the continued safe operation of the aircraft. Under high stress/high workload scenarios the body's demand for oxygen will typically be greater. Their oxygen supply is provided from their own bank of cylinders located below floor level in close proximity to the flight deck, the exact location varies according to aircraft type. Without knowledge or respect for TUCs and the effects of hypoxia, a crew member might erroneously elect to first address an important aircraft warning system before fitting their oxygen mask, deeming their mask to be a lower priority when the opposite is true. If they chose to take that sequence of action, they would quickly become incapacitated before they realised or even cared, succumbing swiftly to the effects of hypoxia. If they’re not assisted and provided with an oxygen mask by another person (who’s already on oxygen), they will lose consciousness after ineffectively dithering only a couple of minutes or less, and within 3-4 minutes more they will die! Hopefully that information is of interest to any reader, and supports the already great explanation of respiratory pressure differential provided by the producer.

    i think the shorter explaination is needed because not all ppl understand about how lung works and its medical terminology. . basically ppl can survive in aircraft at high altitude thanks to enclosed cabin that makes environment liveable for humans up there. if this cabin got a leak, theres supposed to be a warning blaring, but without evidence we dont know what the pilots doing as explained in video, theres no certain evidence as the crash is so violent it destroyed most important parts to be investigated. . in short, the aircraft design is probably prone to have pressurization issues which needs to have different regulation for this type of aircraft

    Some pilots will often remove the starboard aft escape window to load baggage. Often golf clubs, as to not damage the interior. A damaged escape window seal would cause lost of cabin pressure. This leak could be slow at lower altitude and worsened at high altitude, fooling the pilots.

    Those pilot reported discrepancies should be mandatory. "Several anomalies"? Ground checking the system to see why this was happening, but no real conclusion? Yet they put it in the air after general cleaning? It was heartbreaking when Payne died, as well as all others on board. The possible pilot reports, I think could have changed everything. While piloting the plane, if this incident occurred there would be eyeballs and attention to detail that might have been helpful. Like timing, origins of event, and execution of back up system used to change the event. Signs to look out for etc. Am I wrong about that?
