  1. Where does it say no night tandems? http://www.strongparachutes.com/events/mosttandems.php Sparky My idea of a fair fight is clubbing baby seals
  2. PM me an email address and I will send you a PDF copy of the manual. Sparky My idea of a fair fight is clubbing baby seals
  3. Jerry, Bill, Sunrise and Sunpath are both certified under TSO-C23d. They were tested to the standards set forth in AS8015 Rev. B which makes direct reference to the testing of RSL’s if used. 2.1.8 RESERVE STATIC LINE: A device connected to the main canopy that is capable of actuating the reserve parachute assembly following a breakaway from the main canopy. 4.1.4 Primary Actuation Device/Ripcord/Reserve Static Line: The primary actuation device/ripcord/reserve static line, including all joints, shall withstand the test loads of 4.3.1 without failure and shall meet the functional requirements of 4.3.2. Skyhook, by definition, is a variant of RSL’s and would fall under these testing requirements. Sparky Having been involved in a couple of TSO programs I, for two, could not agree more.

  4. Well Dingle Berry, I may be a moron, a dorkzoner (since you are posting here I guess that makes you one) and several other names I have been called. But I have survived 30 years in a sport that has a habit of putting chest beating, loud mouth beginners in a body bag. Like the last poster said, it’s your attitude that will get you killed. I give you 7 years. Now you stay safe and don’t forget to pull. Sparky My idea of a fair fight is clubbing baby seals
  5. They are called “Private Messages” because they are private. It is tacky to post PM’s on an open forum. Sparky My idea of a fair fight is clubbing baby seals
  6. Steve, +1 I spent 30 years fighting fire in So. Cal. Sparky My idea of a fair fight is clubbing baby seals
  7. I am not sure, let me get my glasses and take a better look. Sparky My idea of a fair fight is clubbing baby seals
  8. Thanks Jerry. One change leads to another change that leads to another change............ Sparky My idea of a fair fight is clubbing baby seals
  9. You are right but we were talking about one that had an RSL on it. I guess what I meant was that to have Vector II RSL it needs the ripcord with the eye to be approved. Sparky My idea of a fair fight is clubbing baby seals
  10. Para Gear prices are and always have been over the top but their inventory is the best in the industry. In 30 years I have found their turn around time to be as good or better than any other source and they will sell is small lots. I have had to return items both my fault and theirs but have never once felt like I was not treated as a valued customer. This is just my experience and your mileage may vary. Maybe your expectations of customer service are a bit high. Sparky My idea of a fair fight is clubbing baby seals
  11. John, behave yourself. Sparky My idea of a fair fight is clubbing baby seals
  12. I can see what appears to be a “last hope rope” made of 550. Is the yellow 1” tubular hooked up like an old Stevens’s system? Is it attached to the housing or to the cable? Sparky My idea of a fair fight is clubbing baby seals
  13. Rich, Back a 100 years or so, when I was an S&TA at Perris a D lic. was required to compete with the big boys at the nationals. There are a whole bunch of D's out there that were gotten just for that reason. Then the whinning stated and it was changed back. Sparky My idea of a fair fight is clubbing baby seals
  14. Over the years the lessons learned at Mann Gulch were forgotten or ignored. In 1994 14 more were lost on Storm King Mountain in Colorado. It was almost the same set of circumstances. Sparky My idea of a fair fight is clubbing baby seals
  15. Not only a non-approved RSL but the reserve ripcord is not approved. Vector 2 ripcords have an elylet at the end not a pin. Sparky My idea of a fair fight is clubbing baby seals
  16. Goggles, I heard a rumor that you didn’t wear no goggles. Sparky My idea of a fair fight is clubbing baby seals
  17. No more calls, we have a winner. Its all in the details. Sparky My idea of a fair fight is clubbing baby seals
  18. I think I see a deal in the making. Sparky My idea of a fair fight is clubbing baby seals
  19. Then I would say that puts the both of them in the same shit pile. Lack of character is not a reason to change the exiting requirements. Sparky My idea of a fair fight is clubbing baby seals
  20. 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. 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.). See attachment 1. (source Flight Surgeon’s Manual) TIME OF USEFUL CONSCIOUSNESS The time of useful consciousness is that period between an individual’s sudden deprivation of oxygen at a given altitude and the onset of physical or mental impairment which prohibits his taking rational action. It represents the time during which the individual can recognize his problem and reestablish an oxygen supply, initiate a descent to lower altitude, or take other corrective action. Time of useful consciousness is also referred to as effective performance time (EPT). The time of useful consciousness is primarily related to altitude, but it is also influenced by individual tolerances, physical activity, the way in which the hypoxia is produced and the environmental conditions prior to exposure. Average times of useful consciousness at rest and with moderate activity at various altitudes are shown in Table 1-8. The subjects were breathing oxygen and produced the hypoxic environments by disconnection their masks. If an individual breathing air is suddenly decompressed; his time of useful consciousness is shorter than if he had been breathing oxygen. The PO2 in his lungs drops immediately to a level dependent only on the final altitude, rather than dropping gradually with each breathe of air, dependent on lung volume, dilution of that volume, and altitude.

  21. Canopies may have changed but the requirement to land it accurately has not. These requirements were written when everyone jumped rounds and were able to legitimately get their license. It would be just one more example of “dumbing down” to meet the “no child left behind” theory. Are we going to reduce or eliminate every requirement that someone finds “too hard”?

  22. That is your opinion and your opinions are not the requirements for a C license. And then people wonder why newer jumpers feel it is acceptable to cheat in other areas sicnce they have learned cheating from their instructors. But you expect everyone to live down to your standards. Sparky My idea of a fair fight is clubbing baby seals
  23. Now this is a great reply. See attachment. Sparky My idea of a fair fight is clubbing baby seals
  24. How do you know you have 5500 jumps and not 5600 or 5100 jumps? Is 5500 just a guess? Sparky My idea of a fair fight is clubbing baby seals
  25. When you get right down to it a log book is only important to the person who owns it. It is a record of what you have accomplished, where you have been and people you have met along the way. It can also be a reflection of a person’s character. If a person will lie to himself in something like a skydiving log book he will lie to just about anyone about anything. As was mentioned, in the last few years it seems to be on the increase. It just might be that the “entitlement generation” feels it there “right” to falsify records, official or not. As others have stated, you are to be commended for going with integrity over what amounts to lying and cheating. Sparky My idea of a fair fight is clubbing baby seals
