1. ## Needed a cutaway

What? Nobody thought to collapse the parachute before they left the plane over-night? All you need to do is pull in one suspension line and knot the top to the bottom. That will prevent it from full re-inflating.
2. ## Jumping in metres

Dear iranianjumper, The last thing you want is students fixating on mathematical calculations as they rapidly fall towards the planet. May I suggest reducing confusion by loaning wrist-mounted, metric altimeters to your students? Instructors can wear two altimetres: whatever they like on their wrist along with a metric altimeter on their chest strap. Their student should be able to read an instructor's chest-mounted altimeter if it has a big enough face. If you want to simplify discussions with your pilot. stick an extra metric altimeter to the dash board and ask your pilot to "zero" it before take-off. Your pilot will keep his/her regular altimeter set to feet above sea level because that is what other pilots and air traffic controllers understand. When I used to jump in France and Germany, I still wore my "feet" altimeter and did rough calculations (3 to 1) to confirm that I was "singing from the same sheet of music" as my companions wearing metric altimeters. In the end, it makes little difference whether you pull at 1 kilometre or 3,300 feet or 3,000 feet because the canopy ride lasts about the same number of minutes.
3. ## got injured on jump #24

Hint: if you quit smoking. your bones will heal quicker. The problem is that carbon monoxide (found in smoke) kills the tiny capillary blood vessels that supply nutrients to all of your cells. The fewer your capillaries, the slower you heal. One of the scariest things I ever heard was a surgeon wandering around the room mumbling "You are 53 years old but you do not smoke ... you are 53 years old but you do not smoke ...." Fortunately he decided to operate on my knee bone and it has not dislocated since.
4. ## Prepping?

How long could a homeless person live out of your bug-out bag? I ask because mine was stolen out of my car and I am now assembling a new bug-out bag. My old bug-out bag contained my favourite sleeping bag, matches, knife, flashlight, canteen, canned food, my favourite rain coat, toque, running shoes, spare socks and undies,
5. ## Prepping?

Dear wmw999, Glad to hear that you have at least three choices of where to live after TSHTF. What sort of supplies do you keep in your RV? Any suggestions about "stealth camping" in an RV or van?
6. ## Prepping?

Just this morning, President Trump warned against violence by left-wing Antifa nearing the November election. Granted, antifa may be a bunch of violent thugs with little political agenda. Many antifa members just enjoy a good riot. OTOH, I fear right-wing KKK just as much. Sad how American society has polarized under President Trump's reign.

Dear Murps2000, Stay close to those old folks because they might be able to teach you a thing or two ... cat food stew anyone????
9. ## First time jumping with glasses

Bugeye Bobsters look good. A dozen other companies offer prescription goggles for motorcycling, bicycling and other high-speed sports. I have worn Wiley-X prescription goggles for the last decade. Most prescription sports goggles already come with an elastic strap that routes around the back of your head. Perhaps you should get a pair of bicycling-specific prescription goggles and wear them for a few weeks of cycling before wearing them on a jump. Just remember that skydiving exposes goggles to far more wind than the fastest bicycle. Your dilemma reminds me of a pilot emergency parachute customer who owned two airplanes and four pairs of glasses. One airplane had a nose-wheel (CJ-6) so landed almost flat while his other airplane was a tail-dragger (Globe Swift) which landed nose-high. He had prescription reading glasses and prescription driving glasses. He had two more pairs with dark lenses and said that the most frustrating part was when he was flaring for landing - at dusk - and suddenly remembered that he was wearing the wrong par of glasses! Hah! Hah! Fianlly, when flaring for landing, keep your eyes on the far end of the runway/landing field.

Did you buy the harness new ... custom-built for your body? Most fit problems arise with second owners who are a different size. Also remember that total height is not an accurate measurement of spine length or harness (MLW) length. First ask a rigger to see how well the harness fits you.
11. ## British Columbia provincial election in October 202

Yes dear SkyDekker, The B.C. Provincial "Liberal" Party is out of phase with all the other liberal parties in Canada. B.C.Libs are more of a conservative party representing big business interests. OTOH LIberal parties in the rest of Canada tend to be slightly left of centre, but not as far left as New Democrats. Keep in mind that major political parties have plenty of overlap in their policies. Conservative incumbents often enact the most popular, left-leaning NDP policies to steal votes.
12. ## Is it normal for AFF students to not care?

That blase' atitude is rare among skydiving students. The vast majority listen carefully in class and try to perform well during their first jump. Have trained hundreds of static-line and IAD first jump students. I have also done hundreds of Progressive Freefall (harness hold) jumps with first time freefallers. I can only count on one hand my number of freefall jumps with first timers (AFF). Oh! ... and I have done more than 4,000 tandem jumps with first-timers. I definitely prefer starting students in a wind tunnel, a few IAD jumps (until they land decently) then take them up for their first freefall. No single method is perfect ... just "best" at one stage in the learning process.
13. ## Tandems & outside video & FARS

I agree with you. Too many DZs are desperate for outside videographers so that as soon as a sport jumper has 300 jumps, he starts videoing tandems. After one arrogant flew directly over my drogue, he never jumped with me again. The video only showed fingers and toes extending beyond the drogue. I would much rather strap a camera to my hand - and double the TI's work-load - than be chased by a junior jumper. Originally, tandem manufacturers restricted videographers to TIs or AFFIs. This was just a polite way of saying "If you have to ask, you do not understand the risks."
14. ## British Columbia provincial election in October 202

Premier Bill Horgan (New Democratic Party) just called a snap provincial election for late October 2020. This election is a year ahead of the end NDP's 4-year mandate. Perhaps Horgan is hoping to get re-elected on the basis of handling the COVID 19 epidemic better than most provinces. Did I ever tell you how much I hate the Canadian tradition of the incumbent party calling an election any time they damned well please? Good new is that this election is in October. Many Canadians are hoping for predictable elections in October. The best part about an October election is that we have an excuse not to listen to media blabber about the American Presidential election in November. Why should we get excited about an election we have no vote in? P.S. New Democrats are slightly farther left than Liberals.

Last thing I heard was that Judy and Bob Celaya moved up to Tehachapi, California, a few miles up the hill from Mojave and California City.
17. ## Need Experienced Opinions on Used Skydiving Rig, Jump Suit, Camera Gear, Helmet etc from an Estate Sale.

yes dear F104 Starfighter, I am a semi-retired parachute rigger. I hold American, FAA Master rigger ratings for back, seat and chest. I have also packed a couple of lap type parachutes. I Held Canadian Rigger A, Rigger B, Rigger Instructor and Rigger Examiner ratings. Since I live in Canada, I can only offer you advice over the intenet. All the other comments are legitimate. I suggest that you telephone Action Air at Yolo County Airport, near Sacramento and schedule a visit. Or contact Pete Swan, a Master Rigger who works near Lodi. P.S. Back when I was young and beautiful - circa 1985 - I helped ship some of the last Canadian-built CF-104 Starfighters to the Turkish Air Force.
18. ## Need Experienced Opinions on Used Skydiving Rig, Jump Suit, Camera Gear, Helmet etc from an Estate Sale.

Yes! Please post photos of the reserve packing data cards. They are hidden in a pocket just above the label.
19. ## total knee replacement

I had knee surgery 6 years ago. My knee started dis-locating 5 years afteer an airplane crash. Doctors diagnosed me with three torn ligaments in my left knee. Since they could not repair my posterior cruxiate ligament, they re-aligned the top of my tibia. In the months leading up to surgery, I did plenty of half-hour hikes to build up my leg muscles and stamina. Unfortunately, I could not afford physio-therapy, so my healing process was considerably delayed. Since knee surgery, I did another 300 tandem jumps, then retired from skydiving.
20. ## What forces act on slider?

Sliders are forced down by the canopy inflating and spreading lines wider. Cascaded lines help add - a little - spreading force early in the inflation process.
21. ## Tension knot or something more

The easiest way to keep suspension lines neat is applying a bit of tension.Gravity is your friend. PRO -packing helps as long as all the lines are evenly tensioned between your shoulder/hook and the harness. A wise man can learn from even the village idiot.
22. ## Tension knot or something more

Bill Booth likes to remind us that packing a ram-air canopy is basically about straightening out the strings. Once strings are straight, it will want to open. Failing to clear stabilizers - outside of lines - was your buddy's first mistake. Yes, twisted steering lines are more likely to create tension knots.
23. ## RDS vs full RDS

Traditional parachutes have their pilot-chutes and deployment bags semi-permanently attached to the canopy via a knot or connector link. Split sliders are fashionable with 3 centimetre precision landing competitors because they allow risers to spread wider, improving lateral stability. Nowadays, many PA competitors just pull sliders down to neck level. Collapsible sliders were the next invention, primarily to reduce vibrations as wing-loadings exceeded 1 pound per square foot during the 1990s. That vibration also prematurely wore out the bottom of suspension lines. Removeable sliders were briefly fashionable before pond swooping became a hard-core, niche competition event. Then they added extra-long bridles that connect sliders to d-bags. With full-blown RDS, the d-bag and pilot-chute are not linked to the canopy. Once open, they just trail behind.
24. ## Why different actions when Two canopies out

WE teach students to steer the front canopy when both inflate. We also teach them to steer very, very gently.
25. ## Taiwan FAA Riggers

Try asking around US military bases.
