  1. That reminds me of my ex-wife. She had an abortion many years before I met her. She got the abortion because a child would have been "inconvenient." After meeting her mother and observing the two for a few years, I concluded that my ex- would have done a terrible job of raising children. Thankfully I never got her pregnant.
  2. Excellent video dear Binary93! That is why I always clamp my knees together and tuck my elbows in to reduce the width of my suit as the pilot-chute tries to deploy my main canopy. Now a little history. Back circa 1980, huge balloon-suits were fashionable for (belly-flying) freefall formations. Those balloon-suits were so huge that spring-loaded pilot-chutes often hesitated in their huge burbles. That is when a variety of hand-deployed pilot-chutes (pull-out and throw-out) were invented to get PCs out to arms' length before releasing them. Hand-deploys decreased the incidence of pilot-chute hesitations. Fast forward to 2000 and modern wing-suits were introduced. First-adopter WS jumpers quickly realized that throw-out PCs were far more reliable.
  3. Dear Deyan, Tensile testing is easy because it is the same test for acid-mesh and PD reserves: 40 pounds. Measuring porosity is slightly more difficult, but just ask the tester for raw porosity numbers. If porosity is less than 3 cubic feet per minute, your canopy is still within the original manufacturing specifications.
  4. Try asking another factory (e.g. Performance Designs) to re-certify your old Decelerator reserve. Alternately, ask one of the Strong Tandem re-certification facilities to test your old reserve. Both manufacturers test for tensile strength and porosity.
  5. Paxton Smith spoke with courage, truth and clarity.
  6. Chances are that you unintentionally folded your legs and that created the imbalance. Alternately, extending your arms high above your head might produce the same instability.
  7. Yes, rent gear from your local school for a few jumps. Then look at low pack volume main canopies. They pack one size smaller than regular ZP main canopies. For example, if your old Vector will hold a ZP 190, then it can also hold a LPV ZP 210. Everybody jumps ZP mains these days. LPV reserves are also available. I just assembled and packed an LPV Optimum 215 reserve into a Vector 3 that previously contained a Smart 190 reserve. It may be possible to update your old Vector II by adding a BOC, bridle cover and Cypres pockets. Al sot everybody jumps with an electronic automatic activation (Cypres, MarrS, Vigil, etc.) device these days.
  8. What do you call a bear with no teeth? A gummy bear!
  9. Low pack volume fabrics allow you to pack a 310 square foot canopy into a container designed to hold a 280. These canopies are as strong, and fly similar to canopies made of old-style F-111. Zero porosity, low pack volume fabrics fly and flare and last similar to old-style ZP fabric. I just packed a Performance Designs Optimum 215 reserve into a container that previously held a Smart 190 canopy. The container was snug around the Smart. It previously had been ridiculously tight around a Fury 220 resefve with Dacron suspension lines. The Optimum reserve's low pack volume fabric is easier to compress and made for a neater pack job even if the final product weighs the same.
  10. Skydiving gear has converged during this century. The vast majority of skydivers now jump kill-line pilot-chutes stowed in Spandex pockets sewn to the bottom of container. Pilot-chute diameter varies between 26 and 36 inches depending upon the weight of the main container and expected speed at deployment time. People debate the advantages of F-111 versus ZP fabric, but ZP provides more consistent openings. Deoployment bags usually stow most of their suspension lines in pockets closed with tuck tabs. Only two rubber bands lock the bag closed.
  11. What is the difference between parachute riggers and lawyers? Riggers care if their clients are still alive!
  12. "Stagger" means that the lateral strap is sewn to the hip joint above the (short) upper leg strap. "Stagger" often causes the container to ride higher on your back. If your shoulders are stiff, this might make it difficult to reach your BOC.
  13. Let's see if I can remember this off the top of my head .... Back when I was the busiest Rigger Instructor in Canada, I followed CSPA's Rigger A Course outline: Introduction course outline regulations What do riggers do? Basic parachute design and configurations Materials Harness/container components Pilot chutes Deployment devices with emphasis on D-bags Risers and 3-Ring releases Square parachute nomenclature AADs with emphasis on Cypres 2 Packing demonstration (by an instructor) followed by practical exercises Assembling components Minor repairs Equipment selection exercise Written exam Final practical exam Wrap up
  14. More than one Scottish soldier has jumped in a kilt. They fasten leg straps first, then wrap their kilts over top. If you want to jump in a long wedding dress, make it out of very porous lace so that wind can blow through it.
  15. One of my skydiving buddies liked to experiment with recreational pharmaceuticals. When he over-dosed, I took him to the hospital. As the doctor examined him, he asked several questions: "Do you see pink elephants?" "No" Do you see orange rhinosaurus?" "No" "Do you see green Martians?" "No." Then the doctor says "It looks like will be okay. Just rest of a few days." and wandered off. I turned to my buddy and said "You are way sicker than you look. The room is full of pink elephants, orange rhinosaurus and green Martians!"
  16. Amusing how it attaches suspension lines to mini-flares. Note that these mini-flares are far broader than those used by Flight Concepts. They are conceptually more like the broad flares on Para-Foils and other early ram-air canopies.
  17. Returning to the original question ... If someone slanders or defames an institution (school, church, corporation, etc.) they can be sued for slander. For example, a few years ago a driver slandered Coast Mountain Bus company on social media. Since he was a new-hire - still on probation - they fired him.
  18. Speaking of pot and university towns ... I was driving on the interstate near Eugene, Oregon when I noticed my gas gauge getting low, so I pulled in to town and noticed how foggy it was in Eugene. While pumping gas, I noticed the smell of marijuana and I got the munchies. I knew that the guy working in Subway was a stoner when he licked the edge of the paper before rolling it around my sandwich. Then he said "Flash it up." A few minutes later a cop pulled me over and saw the sandwich with one burnt end. He asked if I had any marijuana in my car. I replied "search me." When He did not find any pot in my car, the cop sold me some.
  19. I vote FOR vaccine passports. Mind you, I got vaccinated on Monday ... Moderna ... via my employer ... I am over 63 years old.
  20. Dear oldwomanc6, Try those blunt-ended shears favored by emergency medical technicians. They can quickly de-pants the wounded with minimal risk of damaged flesh.
  21. Dear Stratoflyer, I would just patch it with a piece of slider tape. You can sew on a patch without picking any stitching out of the binding tape.
  22. That can be patched without opening the side seam. Start with a piece of slider tape bigger than the tear. Secure the outboard edge by sewing a piece of slider tape on the outside. Make those rows of stitching directly on top of the stitch rows on the binding tape. Then sew the patch to the pocket. .
  23. If it is new-manufacture, send it back to Sun Path for a "warranty repair." Your local Master Rigger might be able to build you new main lift webs, but they will not be as precise as factory MLWs.
  24. Dear a105r, I was joking about quickly cutting off a jump suit to prevent a fatality. I was being silly yesterday.
  25. Lesson learned: Always carry a hook knife or scissors in your jumpsuit.
