I am surprised every time I see this picture pop up. I helped design the harness pictured based off my need for it. The guy in the picture, Mike F., did the sewing based off of my design and jumped his FEMA dog, Cara (pictured) at the WFFC in Rantoul in 2005. I was there for this jump and when they landed. Mike went on to sell this harness to K9 storm I believe. I've seen a few variations of the photo where some one has photoshopped the moral patch seen on it (USSO) and another different one. There was no moral patch on the harness when the jump was made.
 
Soldiers having fun, some of these clips are funny.

Very cool picture. Does the dog get any supplemental O2?
 
Cara had supplemental O2 via a vet sedation mask for the entire pre breath and during the plane ride to altitude. Since there was no good way to keep it on her during freefall along with a bail out bottle, she came off O2 just prior to exit.

So the dog had nothing to breathe while falling? Am I reading this correctly? I never jumped out of a perfectly good aircraft so am trying to figure it out. I know what HALO/HAHO means. At what altitude would you need O2? About 15k-16k?

Contrary to what some people believe and urban myth, you can breath in freefall, so Cara was able to breath during the decent. The danger of hypoxia isn't as big of a deal as she was a passenger and her limited exposure time was within safe working times. The threat of a Nitrogen related issue was mitigated by her (and the jumpers) pre breathing 100% O2 for 30 mins on the ground and during the aircraft ride to altitude. Cara also wore specially made goggles called doggles for her eyes and paw protector shoes for the pads of her feet. If you google search the jump (I imagine it is still out there), you can see video footage from the freefall and as they land.

The need for supplimental O2 during flight and while in freefall starts at 13k feet if you will be at that altitude for 30 mins or longer (FAA standard) and only requires a nasal cannula, which is not suitable for altitudes of 18K and up, or for military operations. The military altitude ceiling standard for mandatory use of supplimental O2 is slightly higher than 13K feet for 30 mins and the old 18K pre breath ceiling was also raised a few years back to adjust to modern training and equipment capabilities along with updated physiological studies related to high altitude flying/parachuting in the military.

There have been a few guys who have climbed Mt. Everest (29000ft) without supplemental oxygen. They are exerting themselves much more and for a longer duration then a skydiver would. I think the danger zone for hypoxia is above 26000ft. But again, your physiological background, exertion, fitness, training, etc. all affect how long you can stay there.

The danger zone for hypoxia starts at 15K

It's not an apple to apple comparison to look at mountaineering and military high altitude parachuting. The danger for military parachutists isn't hypoxia so much as it is the Nitrogen related issues (ie: the bends) due to the rapid ascent/climb of an aircraft vs the weeks it takes a climber to ascend/descend so his body acclimates. Hence the parachutists pre breathing 100% O2 for 30 mins prior to ascending above 20k to reduce the amount of nitrogen in the body, as it will expand in the soft tissues as you rapidly ascend if not reduced/removed.

There is no set in stone altitude for hypoxia, as it is physiologically based on the person. If you are a smoker, poor health, lacking sleep,meds,diet, etc can influence when or if one person goes hypoxic and others are OK. It is generally agreed on that 13K feet MSL is the altitude to consider it as that is what the FAA Flight Level stipulates when operating an aircraft for more than 30 mins. That is not to say someone can't get hypoxic at a lower altitude as it happens all the time, just watch those low landers who try and walk up Pikes peak or try and do their normal work out at a higher altitude prior to acclimatization.Technically, when you yawn, you are experiencing a form of hypoxia.

mountaineering/parachuting/diving each have their specific issues when working at mids to extreme altitudes/depths. You cannot group them all together and assume what applies to one applies to the others across the board, it doesn't work that way. All of this is based on human physiology and laws of nature ,like Boyles law for example.


EDIT: OH YEAH, almost forgot....BOOBS!! :D
