  1. Poverty has always been against the law. Stereotyping one skin colour - as more likely to be poor and criminal - is a lazy cops' way of identifying criminals. OTOH profiling potential criminals by listening to them, noticing their clothing, the type of car they drive, driving habits, work history, drinking habits, smoking habits, drug habits, wife-beating habits, daily habits, associates, fancy hand-shakes, etc. takes weeks or months of careful observation.
  2. Dear Biggun, Police near my home town profiled ... er ... banned motorcycles from main street for good reason. For the last half-century, certain groups of motorcycle enthusiasts who prefer not to be mentioned in public dominated the drug and prostitution business in the Province of Quebec. Different groups killed each other and even killed rogue members of their own gangs. One group bought a club house near where the city limits of my home town abutted the city limits of a neighbouring city. There was only one road (paralleling a river and railway line and a steep wooded hillside) between the two towns, so police banned motorcycles from Wellington Street. When I unintentionally violated that law, a city police constable politely told me about the law and suggested a route off Wellington Street. He did not hassle me because my cafe racer had out-of-province license plates and did not even vaguely resemble the rides preferred criminal motorcycle gangs. Since I was clearly from out-of-province, he even talked to me in English.
  3. last thing I heard, the Conatsers (Perris Valley, California) flew their DC-9 until it needed an expensive engine change. The plane has been grounded since then. Lots of Air Forces allow thousands of jumps per year from their jet transports, but you have to enlist before you can enjoy those jumps.
  4. Hint! Chuting Star features T-packing stakes in some of their ads. Try calling Chuting Star.
  5. Follow your doctor's advice and hire a personal trainer to teach you the correct way to dead-lift without risking re-injury.
  6. Old airplanes wear out or corrode out. I was badly injured when a 40 year old King Air suffered a fuel pump failure. A skipped inspection almost killed us all! After 3 -ish years, the factory's liability fades and then the reliability of any machine becomes increasingly dependent upon the thoroughness of the last mechanic. For example, if the owner does 1,000 jumps per year - in the Southern California desert - a parachute might be scrap after 3 years. OTOH Closet Queens might be in mint condition after 30 or 40 years. However, Closet Queens may need Special Inspections or Service Bulletins that were published long before the interweb became popular. That is why young riggers should not feel forced to repack any parachute older than themselves. As for the grey-bearded, grumpy old Master Riggers ... I refuse to repack plenty of gear that was fashionable when I started jumping: round reserves suspected of acid-mesh, first generation 5-cell square reserves, Sentinel AADs, pre-3-Ring canopy releases, etc.
  7. The story is vague. Was Gudmonson being treated at a mental health facility BEFORE or AFTER he was arrested?
  8. How many suspects succeed in violently fleeing police? Do they succeed one day? Do they succeed one week? Do they succeed one year?
  9. if your parents named you after their favourite vice .... For example, one of my co-workers was named "Sherry" by her alcoholic father.
  10. Back during the 1990s, various fabric mills tried to duplicate Parachutes de France's zero porosity fabric ... with varying degrees of success. Gelvenor Fabric Mills in South Africa introduced their ZP fabric that was less slippery than competitors. Gelvenor depended more on calenderizing than silicon coating. Calenderizinf involves pressing the fabric between two heated rollers to partially melt threads and encourage threads to better fill in gaps between them, reducing porosity. This form of calenderizing created a less-slippery fabric that was easier to pack. It also needed less silicone to reduce porosity to zero. Gelvenor's disadvantage was wide variations in fabric bulk. Early Triathlons (sewn by Parachute Industries of South Africa) varied as much as 30 percent in volume. This drove container manufacturers to drink! Hah! Hah!
  11. Koji learned a bloody lesson so that we don't have to. Koji re-used the same set of main Slinks on 3 or 4 different line sets. Eventually a sharp edge on a slider grommet cut off the tab and the Slink separated as he turned on to final approach. Koji is spending the rest of his life in a wheelchair. Granted that was a maintenance problem. But hand-tacking reserve Slinks is still a good habit ... er ... best business practice ... to doubly ensure that a Slink does not separate. Hand-tacking Slinks may be over-kill, but I still do it on every reserve. I only tack the tab and try to leave enough slack to allow pulling the tab close enough to the edge to allow the next rigger to inspect the Lark's Head knot during every subsequent inspection.
  12. Paul Thorn has a funny song entitled "I don't like everyone I love."
  13. I echo the OP's experience. I started skydiving back in 1977 and earned my first tandem instructor rating in 1986. From 1992 to 2010 (18 years) I worked full-time in the skydiving industry, often "8 days a week." I did tandems on weekends and rigged from Monday to Friday. It was only after 10 years, that I was able to negotiate 1 day per week as a rest day. Otherwise, I had to be on the DZ everyday and ready to jump with students. If weather turned nasty, I busied myself in the loft. A few years back I heard a younger TI complain that she was exhausted by the end of July and just dragged her ass through August and September. When the rainy season returned in October, she suffered major depression. Over the winter, I supported myself rigging and preparing 50-some-odd school rigs for the next season. For many years, I was the only Canadian skydiver collecting a salary 12 months out of the year. It was not so much burn-out that forced me to leave the skydiving industry as it was injuries suffered during a plane crash. I recovered from most of my physical injuries after a year, but never recovered psychologically. I was more bored than stressed 3 months after the crash, but then too many lawyers, bullies and fiercely competitive skydivers reminded me of the crash too many times, burning that miserable crash into long-term memory. The worst part of leaving the skydiving industry was sociological. Working those long hours prevented me from forming social connections outside of skydiving, so when I no longer worked as a full-time skydiver, I lost my social circle and huge part of my identity.
  14. Dear ChrisHoward, What if the manufacturer no longer makes spare parts? For example, Rigging Innovations quit building Talon 1s during the mid 1990s and no longer supply Talon 1 spare parts. What is a rigger to do if a Talon 1 is only "lightly used" but loses a freebag and a replacement freebag cannot be found?
  15. LOR was one solution to the problem with main risers breaking - circa 1990. Since 1992, a couple of ways to build stronger Type 17 risers have been published by PIA and 3-Ring Inc. See the thread on 3-Ring drawings. Now broken risers are rare.
  16. I wrote down a long list of things that I aught to do before I die. I call it my authtodobiography.
  17. Amazing how polarized American politics have become. I fear extremists on both sides of the aisle. Russia proved that hard-core, left-wing communism did not work. Hitler and Musilinni proved that hard-core, right-wing fascism did not work. While I might agree with some of Antifa's goals, I fear their violent methods. TV news reports portray Antifa protesters as violent, anarchist thugs. The ultimate Antifa foolishness (a few months back) was masked Antifa thugs harassing an American citizen waving an American flag on the sidewalk outside a coffee shop that refused to serve coffee to police. Sorry if I sound narrow-minded, but if you object to waving an American flag in the USA, I suggest that you leave the USA.
  18. Not sure what the OP is complaining about. Yes, they sound a bit unprofessional. My only confusion is over no response to the transiting private airplane. Were both jump planes shut down when he flew over? The scary, un-professional, dangerous thing is when cross-country airplanes fly directly over a DZ without listening to the local radio frequency.
  19. Some ejection seats use tear-strip bridles to even out surges in opening sequences. Tear-strips function the same way as the cotton break-cord used to stage openings on military static-line mains. Lazy skydivers switched to Velcro, then rubber bands, than sili-stows, then tuck tabs, then magnets, then ... quick! invent another gadget ....! Once airspeeds exceed 200 knots, even the slightest pause in opening shock is quickly followed by a massively harder load surge as different components struggle to match speeds. Those surges tear parachutes and pilots. The simplest tear-strips involve a piece of (full strength) webbing folded over on itself and zig-zag sewn with E-thread. Tearing E-thread is more consistent than the rubber bands suggested above. Since the E-thread consistently fails at 8.5 pounds, it is easy to calculate when it will tear. The problem is protecting that tear-strip until it is needed. Protection is easy inside a sealed ejection seat or reserve container, but more difficult on main risers that are expose during every jump. Perhaps you add a tear-strip just below the 3-Rings and protect it with a fabric cover. ???? Mind you, the most painful openings tend to force all the opening shock onto one side of the harness. This challenge requires a brighter mind than mine.
  20. A few minutes later, the cop was putting hand cuffs on me. "Sir, you have the right to remain silent ... because you have already annoyed me enough today."
  21. Poverty has always been against the law, in most contries.
  22. One theory holds that passing trucks generate swirls that grow into tornadoes. Fewer trucks on the roads equal fewer tornadoes, during the COVID-19 shut-down.
  23. Dear cosmicgypsy, Your profile says that you made 110 jumps. How long ago was your last jump? Did you earn a USPA A License before the pause?
