  1. Forget about resale price. At best, the MARD will make it sell quicker. You need to be alive to sell this rig a couple of years down the road. A MARD slightly improves your chances of surviving the next couple of years. The way to improve your 2020 survival chances is participating in Safety Day refresher training.
  2. Black-coated cable is stiffer, ergo better with spring-loaded pilot-chutes. Black-coated cable is stronger than needed for S/L. Most S/L rigs use flex-pins made of clear-coated cable.
  3. http://Did you hear about the British woman who tried to sue the Natioanl Health Service. She claimed the NHS ruined her love life. She said that she used to sex with her husband - on a regular basis - until he had surgery at the local hospital. Surgeons removed two things from his body: cataracts!
  4. We are all anxious when we jump. The only skydivers who are not anxious are stupid. Stupid skydivers don’t survive very long. As a junior jumper, your challenge is to convert your anxiety energy into “safe” routines, like studying the winds, planning your landing pattern before boarding the airplane, pin checks, looking over your shoulder before turning, etc.
  5. Flex pins are the most idiot-proof way to close static-line rigs, but they are not perfect. When I maintained the gear at a S/L school, I always made sure there were a few spare closing loops and a few spare flex-pins and encouraged packers to replace them at the first sign of significant wear. Key point: flex-pins and closing loops are cheap, but airplane tails are expensive. For tools - as important as hook knives - wise operations double-up or triple-up.
  6. To all those gun-toting, camp-wearing, wannabe soldiers: “You, me and rucksacks ... once around the airfield.”
  7. Cypres 1 should have retired from Canadian DZs a long time ago because Airtec put a 12 year life on them. Airtec quit building Cypres 1 early in this century. Similarly, Canadian skydivers are expected to maintain their gear in accordance with manufacturers' instructions. That includes all Service Buletins, Special Inspections, etc.
  8. This morning, as I put on my shirt, a button fell off. When I picked up my brief-case, the handle fell off. When I tried to turn the door handle, it fell off. Now I am afraid to pee!
  9. Canada has few rigid rules about gear life beyond those specified by manufacturers (e.g. all Cypres 1 AADs should have retired more than 15 years ago). Also review service bulletins. This is really two separate issues. Fortunately, most parachutes wear out before they fall out of fashion. The more complicated problem is when gear remains in service long after it has fallen out of fashion. For example, round reserves should only be worn by POPs who have already landed a few dozen round main canopies. I may have started jumping round canopies - during the 1970s - but my last round landing was in 1986. If you ask me to repack a round reserve today, we will share a laugh! If you ask me to repack a round reserve made during the 1980s, I will explain that I no longer have the tools to test for acid mesh …. and the nearest museum is in Langley. An even greater problem is when junior jumpers want to jump older gear without understanding the limitations. For example, I have advised several skydivers about the dangers of loading Micro Raven 120s more than 1 pound per square foot because no one was loading mains that heavy when Ravens were introduced (circa 1984). As for free-flying with pre-1995 gear, that is just plain dumb because there are far too many opportunities for stuff to blow loose when wind hits it from weird angles. In conclusion, the simple answer is don't jump gear more than 20 years old. The complicated answer is that some 30-year-old gear is still airworthy, but you need a history lesson from a grumpy, old, grey-bearded master rigger to understand the limitations on older gear.
  10. When you die, the electrical energy in your body slows down, passing through gaseous, liquid and eventually solid states. When a new organism (worm) consumes your mortal remains, it converts some of those solids and liquids into electrical energy and the cycle repeats.
  11. All good points dear fcajump, May I add that clean cables are more important than lubricated cables when jumping in the desert? Too much lu do any traps grit on the cable, increasing pull force. That grey-black is oxidation see stainless steel from inside ths spiral-wound housing.
  12. Dear 20KN, PIA standards are considered “industry best practices” and anyone who does not follow them is considered annoying. As for canopy measuring methods ... a bewildering array of canopy measuring methods were used before PIA standardized on Para-Flite’s method. Para-Flite and PIA measure chord straight from the trailing edge to the top leading edge. That was easy to measure on end ribs of square canopies. But after tapered canopies were introduced (circa 1990) it became increasingly difficult to measure inner ribs and do all the math. Perormance Deaigns introduced a simpler method which uses bottom skin chord. By 2001 many other manufacturers (e.g. Icarus) adopted PD’s method, so now PD’s method is the defacto standard for measuring ram-air canopies. IOW that boat sailed 20 years ago. This caused confusion when PD started selling reserve canopies because PD reserves packed bulkier than preceding reserves for two reasons: greater top skin area (than PIA) and more spanwise reinforcing tapes. PD needed span-wise reinforcing tapes because their reserves were the first designed to be loaded more than 1 pound per square foot. IOW PD reserves fly “bigger” than old measuring systems suggest. As for canopy bulk measuring methods ... I used to work alongside Sandy Reid (Rigging Innovations) when he measured large numbers of canopies by the PIA method. Sandy compressed canopies into the PIA standard cylinder, then handed them to me to test-pack into the latest models of Talon containers. Canopy volume - same inflated size from the same manufacturer - varies for a variety of reasons: different thicknesses of fabric, different coatings, different humidity, etc. Bulk varied widely during the early 1990s as various fabric mills learned how to weave zero porosity fabric. Early Triathlons varied as much as 30 percent by volume as Gelvenor Fabric Mills (South Africa) learned how to calendarize and coat fabrics. The other issue is different canopy/container densities recommended by container manufacturers. That fashion has definitely gotten tighter over the last 30 years. Just because the best rigger - at the factory - can a 123-sized reserve reserve into a specific sized container does not mean that Joe Field Rigger can do the same, especially when all the subtle factory tricks are not written down. This becomes doubly difficult when the factory rigger packed in a humid loft while Joe Field Rigger struggles in a bone-dry desert. Humidity can decrease pack volume by easily 10 percent.
  13. Dear Gowlerk, "Turtle Island" was the best guess explanation that native Americans could come up with based on their limited knowledge of geology/astronomy/cosmology, etc. When they lacked measurable knowledge of plate tectonics, that used the "Great Spirit" to fill in the gaps. As human knowledge increases, those gaps get progressively smaller, ergo less need for "God in the gaps." The danger is when a religion/shared world view stagnates and clings to an old belief after that climate/society, etc. have changed around them. Organized religions tend to stagnate, while scientists are constantly challenging old views, peer reviewing and testing new theories. For example, modern surgeons perform operations that were considered "miracles" only a few decades ago.
