  1. All people die, some people die having fun. Trust me, no one dies having fun. They just die. Sparky My idea of a fair fight is clubbing baby seals
  2. Not at all debatable. Sparky My idea of a fair fight is clubbing baby seals
  3. Please tell me Sparky how comparing two adventure sports by use of standard per 100k rate in fatalities is not "rational"? Because Im fairly certain people compare fatality rates between numerous different activities or health risks or other such factors on a fairly common basis. Havent you ever heard a skydiver say, "Im more likely to die driving on the way to the dropzone, than I am skydiving"? So if we can compare mortality rates in traffic accidents with mortality in skydiving accidents, I am fairly certain we can accomplish the same thing between kayaking and skydiving. Put I will be waiting to see how you claim this cant "rationally" happen. Hi! Welcome to 2014! Where most of us have accepted the fact that using the term "retarded" is not socially acceptable. Also you might want to Google the term "mental retardation" which will show you that it is in fact an intellectual disability, or general learning disability. Here is the wiki link for it: http://en.wikipedia.org/wiki/Intellectual_disability I rest my case. Sparky My idea of a fair fight is clubbing baby seals
  4. http://www.startskydiving.com/staff.php Look under staff. Sparky My idea of a fair fight is clubbing baby seals
  5. I can be there in 3+ hours. Sparky My idea of a fair fight is clubbing baby seals
  6. I agree, but now we have to remain members so we can make fun of people, like that one person on Facebook we've remained friends with for that reason. Send me his contact information and I will have a talk with him. Guarantee you will like the results. Sparky My idea of a fair fight is clubbing baby seals
  7. Then one of you would be carring 2 kittys. Sparky My idea of a fair fight is clubbing baby seals
  8. Most of your conversation is not rational. Comparing skydiving to kayaking using your methods is like comparing apples to rocks. It seems to me that you are the only one making an issue of “cool”. Again your conversation is not rational....makes no sense. Maybe you should find out what you are talking about before playing the poor me card. Try not to take a word out of context and apply your bias to it. Mental Retardation is a condition not considered part of a “learning disability”. While all people with mental retardation have a learning disability not all people with a learning disability are mentally retarded. Since this site causes you so much aggravation maybe you should just avoid it. Sparky My idea of a fair fight is clubbing baby seals
  9. But I would ignore advice form a guy who has trouble telling the truth. I already know you are lying about your Lic. # and there are serious doubts that you hold a riggers ticket. Now find a kernel of truth is that. Of course it could be that you are not posting under a real name. Sparky My idea of a fair fight is clubbing baby seals
  10. The decreased partial pressure of oxygen encountered at increasing altitude can quickly lead to incapacitation or death. The lethal effects of acute altitude hypoxia cannot be underestimated. Deaths have occurred at altitude between 17,000 and 20,000 feet. The main purpose of our respiratory process is to supply the lungs and the blood and tissues with adequate oxygen, and to eliminate that carbon dioxide that is generated by the metabolism of the body tissues. Hemoglobin is the oxygen carrying agent of the blood. Oxygen must diffuse from a gaseous state to a dissolved state to combine with the hemoglobin. The oxygen diffuses across the alveolar membrane, through the interstitial fluid and capillary endothelium. Within this capillary, the dissolved oxygen diffuses through the plasma, the red blood cell membrane, and the intracellular fluid within the red cell to combine with the hemoglobin. The solubility of a gas, and its partial pressure, greatly influences its diffusion characteristics. Carbon dioxide is about 25 times more soluble than oxygen in pulmonary tissues and fluids and its capacity for diffusion is about 20 times greater than oxygen. PARTIAL PRESSURE OF OXYGEN The quantities of a gas at various altitudes, expressed in percentages of the atmosphere, has little significance. Percentage represents the relative volume of a gas and not its molecular concentration. Molecular concentration, or partial pressure, determines the availability of the gas to the body. The partial pressure of a gas, in a mixture of gases not interacting with one another, is equal to that pressure that the particular gas would exert if it alone occupied the space taken up by the mixture (Dalton's Law of Partial Pressure). The total pressure of a mixture of gases is the sum of the pressure of the individual gases composing the mixture. The body requires hemoglobin saturations of 87-97 percent and arterial oxygen at 60-100mm Hg (millimeters of mercury) in order to function normally. Below this level the body is hypoxic. The standard pressure at sea level is 760mm Hg. Since oxygen comprises about 21 percent of the air, we would expect the dry air oxygen partial pressure in the lungs to be 159.6mm Hg (760 times 21 percent), but through physiologic processes, the partial pressure of oxygen in the arterial blood is normally about 100mm Hg. Air inhaled into the lungs enters small air sacs (alveolus) where the exchange of oxygen and carbon dioxide occurs. When the partial pressure of the oxygen is higher than it is in the blood, oxygen molecules are picked up by the hemoglobin molecules. This hemoglobin saturation is approximately 97 percent at sea level. The atmospheric pressure decrease at 10,000-foot altitude causes 523mm Hg ambient air pressure resulting in 87 percent hemoglobin saturation and 61mm Hg arterial oxygen.(lower end needed to function normally) At 15,000 feet (429mm Hg) the hemoglobin saturation is 80 percent (we need 87-97 percent for normal functioning), and arterial oxygen is 44mm Hg (the body requires 60-100mm Hg.). The higher you go the less of the oxygen you breathe in passes through the cell walls of the alveolus and your saturation level continues to drop. Above 15,000 msl you need a demand pressure system of some type to function normal. What you think or how you may feel about doesn’t count, it if you are above 10,000 feet MSL you are hypoxic. Symptoms of hypoxia are many and varied. They may also change for the same individual from one exposure to the next. And this doesn’t even get into the subjects such as: Types of hypoxia, the need for pre-breathing and symptoms of DCS. If you want to do jumps at higher altitude do it right. Sparky (Over 25 jumps/tests at or above 25,000 MSL Taught High Altitude Jumping to civilian jumpers for several years.) http://i397.photobucket.com/albums/pp55/mjosparky/Testing/HighAltitude3-1.jpg http://i397.photobucket.com/albums/pp55/mjosparky/Testing/HighAltitude2-1.jpg My idea of a fair fight is clubbing baby seals

  12. That, sir, is wishful thinking! And you never want to stop thinking. Sparky My idea of a fair fight is clubbing baby seals
  13. Jim, I have told you this before….I am proud to be your friend. Sparky My idea of a fair fight is clubbing baby seals
  14. When you said something about "do these two look alike?" and "twins" I was expecting something else. Sparky My idea of a fair fight is clubbing baby seals
  15. Kids serve no useful purpose in a modern society… if we lived in a primitive form of society it might be socially acceptable to eat the little bustards. Sparky My idea of a fair fight is clubbing baby seals

  18. Start with this. Sparky My idea of a fair fight is clubbing baby seals
  19. So much advice from so little experience. Contact the major manufactures, they know more about the canopies than anyone you will talk to here, and ask about demos. Talk to the experienced canopy pilots at your DZ and do some demos. Don’t be in a rush. Sparky My idea of a fair fight is clubbing baby seals

  22. With a little practice he could get pretty good at that. Sparky My idea of a fair fight is clubbing baby seals
  23. Thanks Eric, I wasn't aware of that. Yea, I guess that would be on the AAD. Sparky My idea of a fair fight is clubbing baby seals
  24. I would call it a (factory) quality control failure... Did the factory pack the reserve without a cutter? Sparky My idea of a fair fight is clubbing baby seals
  25. Know any? Maybe, they went on to build better canopies? If there is a bad reason why they stopped making Esprit, I definitely would like to know. I wouldn’t call it a bad reason. But they no longer make the CruisAir, the Unit and several other “square” canopies. They came up with better designs, materials and construction methods.
