  1. If you wanted to invent a drogue - to reduce opening shock - you need some sort of speed-sensitive link. ... maybe a drag-sensitive link. Basically, if you toss your drogue/pilot-chute ate more than 130 miles-per-hour, it would remain firmly attached to the harness until you decellerate to slower than 100 mph. Then the drogue dis-connects from the harness and drags your main to line-stretch. Engineers have devoted many millions of dollars to perfecting similar systems for ejection seats.
  2. It caught on the reserve, preventing the reserve from opening. Back around 1990, Ted Strong was trying to develop a new training program that started with tandem jumps, then progressed to droque-stabliized solo freefall, so he installed a drogue on Strong Combination Student container. The drogue was based upon a far more complex design that originated with Soviet Air Force ejection seats, was simplified for Soviet para-troopers, was dumbed down for Russian smoke-jumpers, then dumbed down again for civilian tandems. The solo drogue system worked okay until a student went into a violent spin - in freefall - over Hinckley, Illlinois. When the FXC got scared, it pulled the reserve ripcord, but the round reserve wrapped around the drogue and never opened. End of that idea!
  3. Perfectly normal reaction the first time you do any new scary thing. For most people, the nausia disappears after a few more jumps. Altitude sickness ... errrr ... low oxygen density is rarely a problem during skydiving because few jump planes climb more 14,000 feet above sea level. For comparison, airline cabins are pressurized to 5,000 maybe 8,000 feet ASL, but much of that is to accommodate grandmothers with weak lungs. Time also affects hypoxia (shortage of oxygen), but jump-planes rarely fly more than 5 minutes above 10,000 feet, so that is not an issue for people with healthy lungs. Yes, clearing your ears (Valsalva Maneuver) can reduce sinus pressure, reducing the risk of head aches, nausea, etc. I usually clear my ears two or three times on the way up and once after opening. Low blood sugar can cause nausea ... even fainting ... after opening. We did not understand this until we had been doing tandems for a few years. Basically, any scary sensation causes your body to produce huge amounts of adrenaline and burn through blood sugars at a rapid rate. Once the skydive slows down ... after opening ... you relax, maybe even pass out. The cure is nibbling on snacks and sipping water all day. Also consider that fear levels drop by half during every one of your first few jumps. Fear will never go away, but the curve will flatten out in a logarithmic way. If you get too relaxed, and no longer fear skydiving, then you should quit, because you have lost track of how dangerous the sport really is. Smart skydivers are always a little afraid, but learn how to channel that fear into equipment checks, pre-planning, altitude checks, etc. Older (pre-2000) tandem harnesses were more likely to put too much pressure on your stomach. Modern tandem student harnesses have lower belly bands, so are less likely to cause nausea. If you feel nauseous under a tandem, simply ask your instructor to loosen the belly band a bit after opening. Many tandem students complain about leg straps being too tight, but fail to realize that all their weight is resting on those leg straps. Tough! OTOH loose leg straps can bruise during opening shock, so better for your instructor to tighten leg straps a bit too much ... rather than lose you at opening time.
  4. Hello Ron, If you are treated by the Venterans' Adminstration, then you are on a form of socialized medicine. That is how Canada developed our current MediCare programs. It all started after the First World War when Ottawa established the Veterans' Affairs Department to attend to wounded soldiers' long-term medical problems. After WW2, they extended those benefits to the children of retired soldiers, then the wives of retired soldiers, then eventually every Canadian citizen. Recently, even refugees from Syria have gotten free medical benefits upon arrival because Canadians understand that early medical intervention can prevent chronic illness or disability. Fore example, my church recently sponsored a Syrian family and we donated heavily for dental care because the children had never visited a dentist in their homeland and their teeth were in rough shape.
  5. Agreed Ron, For the last few years, I have visited a medical clinic owned by a pair of Coptic Christians who immigrated from Egypt. They recently hired a third Coptic Christian general physician. One time they had a Nigeria lady doctor working for them temproarily. The most helpful doctor was a South African Boer, so I suspect that he was a Dutch Reformed Christian. I cried when he retired.
  6. Agreeing with most of the posts above PLUS, Dacron lines create more surface friction against each other and slider grommets, because they have a rougher weave. The extra friction could abrade grooves and holes in brass grommets in as few as 400 jumps. The worst case scenario is old, fuzzy Dacron lines that have been jumped too many times in the Southern California desert. The greater the friction, the more likely the tension knots ... more slider hang-ups ... more collapsed end cells ... more broken lines ... more hard openings ... more torn fabric ... etc.
  7. Dear Phil111, Russian population decline is a complex problem with multiple causes. Ripple affects from wars and famines still echo today. Meanwhile, your comments about: abortion, aging and alcoholism are seen as short-term causes. The end result is that Russian population continues to decline, even long after World War 2. Immigration is a further cause. Russia is a cold climate. Far more Russians leave for better lives in First World Countries. Immediately after the USSR collapsed (1989) many Russian ex-pats returned home from former Soviet Republics (Kazackstan, etc.) After that, Russians emmigrated to the First World in increasing numbers. Now, few people want to immigrate to Russia. Part of the problem is white-supremist, skin-head gangs who hassle non-Russian immigrants. The ironic thing is that there is no single, white-skinned, Russian gene pool. Over the centuries, Armenians, Bulgars, Caucasians, Estonians, Finns, Germans, Huns, Jews, Poles,Kazacks, Latts, Mongols, Russ, Scandinavians, Tartars, Turks, Ukrainians, etc. have contributed to the "Russian" gene pool.
  8. Early response to drought/famine is far less expensive than trying to rehabilitate survivors.
  9. Russia would suffer in any trade war involving Russia, China and the USA, because Russia has the smallest population and their population is in decline. One of the causes of Russian low birth rates is ripple effects from all the millions of Russians who died during the Great Patriotic War.
  10. This is silly. I believe in giving credit to inventors. If Uncle Ben invented a rice recipe, then he deserves to have his name on the label. If Aunt Jemima invented a pancake recipe, then she deserves to have her face printed on the box. I do not care about the skin colour of the inventor, because I only care about the taste of the food. If Jack Hooker invented a new type of seat-belt, then I will refer to them as "Hooker Belts. Transport Canada's sissified, limp-wristed, bureaucratic terminology be damned!
  11. 18 years? Wow! My divorce only lasted 7 years.
  12. 20-way out of a Skyvan. Everyone jammed close to the ramp. As we started the exit count, the airplane shuddered and fell off to one side. The formation flew great, but the pilot landed white as a glacier! He explained that the Skyvan stalled then spun one and a half turns before he recovered control. That was the last time anyone jammed an entire 20-way on a Skyvan. The only thing worse is dirt-diving a 20-way from a Skyvan. I have seen two Skyvans bend their tails during that foolishness. Now do you understand why many Skyvans have that extra rail under the ramp?
  13. Okay Ian, Who is operating Skydive Extreme Calgary these days? My last update was from Al Christo shortly before he closed Pitt Meadows, two or three years ago.
  14. Call Skydive Calgary at Beiseker, Alberta.
  15. The Washington Red Skins recently announced that are re-naming the team to a more politically-correct term. ... can't call themselves "Senators" because Ottawa already has a team with that name. How about Washington "Congresscritters?"
  16. Wow! Holy distortion of priorities, Batman! Protest movements usually start when a nation has an excess of young people and a shortage of jobs (see Nazi Germany, 1960s Peace Movement, Arab Spring, etc.). During the Great Depression (1930s) the Canadian and USA governments recognized the problem and set up civilian works programs to convert unemployed labourers in civil infrastructure (TVA, Hoover Dam, etc.). This year, jobs have been limited by the COVID-19 quarantine. The short term solution is bullying protestors into silence while the long term solution is providing more jobs to keep people too busy to protest.
  17. I strongly disagree with westerly .... but I made 1,000 tandem jumps before modern wing-suits were invented (circa 2000). UPY wrote those guidelines to discourage recreational jumpers from chasing tandems after a few collisions killed TIs. Most of the recreational skydivers who ask permission to chase tandems do not understand the extra risks involved. For example, the last time I gave a wing-suiter permission to fly past us under canopy, he passed at a safe and predictable distance. When I pointed out the wing-suit, the student did not seem to care. Shortly after that, the DZO banned wing-suits from "buzzing" tandems. Basic tandems are complicated enough without junior jumpers cluttering up their airspace. I would much rather double my TI work-load by strapping a camera to my hand than trust some unknown skydiver to freefall close to me. This comes from the first hand-cam TI in Canada. I taught myself how to do hand-cam after reading one article in SKYDIVING Magazine. The article described how Australians invented hand-cam. I even sewed my own hand-mount months before I ever saw a hand-mount.
  18. Dear wolfriverjoe, You made a good point about 20 million Russians dying during WW2. Russians are still suffering echos from that miserable war. A Russian man born in 1920 had a 20 percent chance of surviving until the end of WW2. They lost a generation of young men. Which means that Russia never experienced the sort of "Baby Boom" that expanded populations in Canada, USA, etc. 20 years later, the unborn sons of those soldiers did not father any more babies during the 1960s. Twenty years later (mid-1980s) Russia suffered another slump in birth rates. .... another slump in birth rates during the early 2000s, followed by another slump during the 2020s. Four generations later, Russian birth rates are still lower than replacement, so Russian population is still decliniing. Couple this with white-skinned Russians' xenophobia and the country is doomed to declining population. The Great Patriotic War (1939 - 1945) was not "good" from the Russian perspective.
  19. My ex-wife asked why I tried to drive my car over her. I replied that I doubted if I had enough gas to drive around!
  20. My apartment is cluttered with 40 years worth of old parachutes, old manuals, etc. Which museum should I donate then to? Last summer I visited the Canadian War Museum and the Aviation museum at Rockcliffe. More recently, I visited the small museum of aviation in Langley, B.C. I used to jump near the aviation museum in Victoria, B.C. (Pat Bay / Victoria International Airport). Please note that I am a Canadian citizen, living in Canada, who would prefer to donate to a Canadian museum.
  21. Shop-lifting and petty theft. Smoke marijuana and hashish. I started drinking under-age in Saskatchewan and at least 2 other provinces, plus the Northwest Territories. I drove myself home - drunk - hundreds of times. Conversations with 3 different cops when I was DUI, but they never ticketed me. Driven without a license. Driven without insurance. Driven with expired license plates (brief conversation with a police constable, but no written record). Driven a fuel truck with no formal training. Speeding. Roaring through stop signs (got a ticket). Trespassed. Trespassed on a bridge before I fell off. Luckily I wore a parachute. The stupidest thing about that was walking on the autobahn! Crossed a few borders without proper documentation. Fondled and fired a variety of machine-guns after they were prohibited for civilians. Done exhibition jumps from 2,000 feet above sea level. Free fallen through clouds. Flown my canopy through clouds. Done a few night tandems ... er late sunset. Did tandems with under-age girls before they were banned. Done exhibition jumps with tandem students ... before they were banned. Continued VFR flight in miserable visibility. Flew across the Strait of Northumberland, too low to glide to shore .... ' cus of low clouds. Landed after official sunset. Stole an entire car off the side of Burnaby Mountain and am whittling away at the second wrecked car.
  22. Hah! My hand would be on my car's gear shift lever .... as in REVERSE lever. No need for me to stick around while people wave guns in public. Open carry is banned in most parts of Canada .... except in rural areas .... during hunting season.
  23. When catching tandems, I just stand quietly on the edge of the pea gravel bowl until just before they touch down. Then I grab one toggle and run into the wind until the canopy collapses. If steering line cascades get pulled through steering guide rings ... so be it. The primary goal was accomplished by not dragging across the DZ. When I am in the TI's seat, I usually ask students to grab toggles and wait until told, then pull them down to crotch level and continue holding them down. Meanwhile, I reach back, over my head to grab another yard (metre) of steering line to collapse the canopy even quicker.
  24. It is quite common for common criminals to surrender or sell weapons to their lawyers at the start of criminal cases. That allows the accused to claim that he no longer owns any weapons, but with a reasonable chance of regaining the weapons if he wins the trial. Rest assured that lawyers charge a pretty penny for "holding" weapons.
