  1. Read the attachment, it will answer your questions. Sparky My idea of a fair fight is clubbing baby seals
  2. The test is an alternative test to the time requirement. The altitude loss is measurement is measured along a vertical trajectory only. This is usually done with the use of ground cameras. Eight of the test ore done by live breakways with reserve pack opening within 2 seconds of breakaway. If drop tested the speed can range fro 60 KEAS to 110 KEAS.

  3. When you swing, do you always miss by this much? My idea of a fair fight is clubbing baby seals
  4. This could also be looked at in the training of riggers. A more formalized extended program so we do not just produce "parachute packers". jmo Sparky My idea of a fair fight is clubbing baby seals
  5. Communist Vietnamese Honor John Kerry, the War Protestor, as a Hero in the Communist Victory over the United States in the Vietnam War. In the Vietnamese Communist War Remnants Museum (formerly known as the "War Crimes Museum") in Ho Chi Minh City (Saigon), a photograph of John Kerry hangs in a room dedicated to the anti-war activists who helped the Vietnamese Communists win the Vietnam War. The photograph shows Senator Kerry being greeted by the General Secretary of the Communist Party of Vietnam, Comrade Do Muoi. Jeffrey M. Epstein of Vietnam Vets for the Truth acquired the photograph over the Memorial Day weekend as America was commemorating its military heroes. Epstein's organization, Vietnam Vets for the Truth, had issued a general request last week for photographs documenting Kerry's activities on behalf of the enemy. Bob Shirley, a Vietnam Swift Boat veteran (www.pcf45.com), sent the photograph to Epstein in response to that call. Shirley recently joined over 200 other Swift Boat veterans in signing an open letter questioning Kerry's fitness to serve as Commander-in-Chief. My idea of a fair fight is clubbing baby seals
  6. "E" is the thread size and "#69" is the ticket number for commercial nylon thread. V-T-295, MIL-T-7807, "E" thread has a tensile strength of 8.5 pounds and "69" commercial thread has a tensile strength of 10 pounds. Type II (twisted bonded multiple cord), Class I (low elongation), Subclass A (general purpose) is best for parachute work. PPM, Vol. I Have never heard of M40. You might check with Irvin, a British parachute company that I know uses "E" thread. Sparky My idea of a fair fight is clubbing baby seals
  7. I did not bring up blast handles, you did. And I did not bring up quickejects, you did. You may not have said it, but your post strongly implied that price was a way to determine quality. Has there ever been a time when you felt you were in error on any subject? My idea of a fair fight is clubbing baby seals
  8. EXACTLY ! This thread isnt/wasnt about me....it was about those two "classy" people. bozo You are right, Jimbo. Michele and Sparky are two great people. You pick pretty good company! Michele, Sparky, a beer (or other alcoholic concoction) is on me when we meet. Jim, same thing, but I'm thinking "case". Ah Gezzz! I am just naturally a warm and wonderful person. And if you believe that I have some land in FLA. ............ I was kidnapped, Michele said we going to Vegas to me a stripper who liked old men. Sparky My idea of a fair fight is clubbing baby seals
  9. Do you think that is good advise for a greenie to be giving out? bbarnhous had a much better idea. My idea of a fair fight is clubbing baby seals
  10. You are in over your head on this. Performance standards dictate how the rig will work. You can play the word game all you want but a system or the component parts do not "accidentally" pass TSO testing. Have you ever been involved in a TSO testing program? The quickrelease legstrap hardware you mention passed the military "Alpha quals" for use in ejection seats up to around 600 knots. Are you saying they are unsafe for sport rigs? How many have you seen fail on deployment? By your statement you seem to be saying the Dolphin and Genaria are made to a lower quality standard then others on the market. Do you have any information that shows this to be true other then the grommet set problem on the rig you jump? My idea of a fair fight is clubbing baby seals

  13. I thing you are right about the price of a HD. Today you couldn't give them away. Sparky My idea of a fair fight is clubbing baby seals
  14. w/ TSO C23-D they can go as low as 220 pounds, like the PD-106R Derek The test weight must not be less then 264 pounds, and the test weight is maximum operating weight limit(220pounds) x 1.2, that equals 264 pounds. The test speed must be not less than 180 KEAS, maximum operating speed x 1.2 or 150 KEAS. All tests under 4.3.4 (strength test) must be done with the same canopy, harness, components.

  15. If it turned into a ball of shit, would that be enough trouble for you? Have you even thought about it once? Sparky My idea of a fair fight is clubbing baby seals
  16. ***4) Tell your friends you love them. Often. You never know when they'll be taken away from you. 5) Never stop learning - how to fly new body positions, about your gear, about being safe. 8) The best way to get good at skydiving is... don't die. *** Words to live by.

  17. If this is true, how do they get around the requirments of AS8015 Rev. B speicfied in TSO-C23d? People buy the more expensive one because it is more popular. It is a fashion statement. The Dolphin and the Javelin were designed by the same person and functionally are identical. Harness rings, chrome hardware, your name on the mud flap and a 5 color middle flap do not make a rig safer. AFAIK, there had not been a sports rig manufactured with anything but 3-rings since you have been in the sport. How did the subject of capewells get into a discussion on re-pack cycles?

  18. One of the reasons 2 PC set ups fell from favor is that one will always pull against the other. The first one to catch air went up and would drag the other one along. What was needed to get the PC out of the burble of the big suits was a longer bridle. Most of them were 36" finished. The PC would launch, hit the end of the bridle and rebound back on the the jumper. Sparky My idea of a fair fight is clubbing baby seals
  19. The amount saved on a few yards per canopy is quickly eaten up in the labor costs involved in producing the cascaded lines. Sparky My idea of a fair fight is clubbing baby seals
  20. You just keep thinking that way, and start exploring other possibilities. The advise offered here and at your own DZ comes to you free of charge. But in many cases the people offering it paid a stiff price for the knowledge gained over the years. Parachutes don't know reason from logic and have no memory. So you go ahead and re-invent the wheel. If you fuck up just a little bit, you will die. That premise you can take to the bank. If you survive 5 years in this sport look me up and I will buy you a cold one. I would be interested to know if you still feel we are a bunch of blow hards getting by on folk lore and a SWAG.

  21. No, but my sister has a 1963, split window Stingray. Sparky My idea of a fair fight is clubbing baby seals
  22. But Ron, Most of it is written down and has cool graphs. Not many people want to take the time to look through it or go through the test programs where some of the things are validated. Things will change when he goes out in the real world. Ah, to be cloistered in the velvet blanket of academia. Sparky My idea of a fair fight is clubbing baby seals
  23. When you were learning to drive and someone told you to turn right, did they give a detailed explanation on how rack & pinion steering works? If the information on the different "tweaks" is important to you, make an effort to research the "formal knowledge" on the subject. By discarding advise because you feel it does not have "logic or reason" could lead to you ignoring a small jewel that just might save your ass one day. Tom, That is not off subject. It has a wealth of information in it. And pilot chutes are rounds, just real little ones. Sparky My idea of a fair fight is clubbing baby seals

  25. Having been involved in parachute design and testing for over 20 years, I can assure you there is a vast amount of "formal knowledge" on the details of parachute opening. If you feel this statement "begs the question" you can refer to "Decelerator Systems Technology" the Short course by Helmut G. Heinrich, The Parachute Manual, Vol. I & II by Dan Poynter, "The Aerodynamics and Piloting of High Performance Ram-Air Parachutes" by Jerry Sobieski or go to PD's web site and read some of the Tech. papers there. Just because you are not aware of something does not mean it does not exist. It seems that your conclusions "Beg the question". As you said yourself, "as far as I know". How can you say a statement/advise lacks logic or reason when your experience and knowledge can not determine if the statement/advise is factual. By the way, how do you know Kallend was right and the DZO was wrong? With Kallend's education in physics there is a good chance he is right. But then aren't you using the premises as the conclusion? The knowledge is out there, both formal and antidotal, it just takes the effort to find it. Sparky My idea of a fair fight is clubbing baby seals
