Nope, for anything where the bones are in (more or less) the right place, they will just tape you up. For most fractures these days, they don't even use any bracing or tape, since motion speeds the healing process, and the mend will be stronger. Plus don't forget to self-medicate with lots of beer (and optionally herbal stuff ) and calcium. Wrong. Ribs are left to heal on their own if properly aligned, stable and not impedeing or impaling something else, heart and lungs most importantly. If any fracture is grossly malaligned, it must be reduced and fixed, fixed meaning stabilized. Fractures must remain stable to properly heal; motion of an unstable fracture normally will cause excruciating pain and inefficient healing. This is why both external and internal (halos and tibial rods) fixation may be utilized based on severity and location of a particular fractures. The motion aids healing bit is absolute nonsense, further along in the healing process it may stoke enhanced bone reproduction, but definitely not for some time. There is likely someone with really high pain tolerance that could put pressure on a fractured bone temporarily, but that can cause many long term problems including residual damage, not to mention the potential for deformities. Also, drinking alcohol in excess with a healing fracture, while I know is hard to resist, is generally a bad idea. In part because it is a diuretic and you need the minerals and hydration, but there are more reasons. Smoking cigarettes with a healing fracture, also a really bad idea. There are certain herbs that will work well to relieve pain, some are more well known and harder to come by than others. Body armor may not decrease the rate of fractures that occur from hard openings, but I guess anything is possible. The problem may lie in the fact that the compression rate is too high for all of your abdominal contents and the fracture may be generated by internal pressure from forced overexpansion combined with compression following opening shock rather than excessive external force from a main lift web or chest strap, something has to give. If the hard opening is offheading and your body is "expecting" to go another way, the torsion created will contribute also. I guess it depends on how you look at it. just my .02 Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Can you please not do that? I know of at least two people in my neighbourhood for who the mystery of the BASE packjob is the only thing stopping them from going out and jumping. One of them already procured BASE gear (thanks, random person in California that doesn't do background checks) and refuses to do an FJC. I'm well aware that CR has packing information in their Ram Air manual, but fortunately it takes some effort to find, open and read. Having it in full video glory on SkydivingMovies.com would do more harm than good. Are you also well aware that at least one major manufacturer will sell that information on video? Anyone can purchase the video from their website. Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Can someone with underhung dam experience please pm me as I have a few questions about assessment. I would prefer an experienced colorado jumper if possible as they may be able to answer some specific questions. Thanks. Premier Member IGPA 2009 IGPA Overall Champion WWTAD

I'd feel awesome too if someone brought me an Elmo that size. Hope you're feeling better hecker, that Elmo kicks ass Premier Member IGPA 2009 IGPA Overall Champion WWTAD

.....and I'm sure that you'll see that these threads often degenerate into a time for net nerds to justify their superiority to someone who knows no better Sometimes it's an opportunity to let their own thoughts wander aimlessly (pointlessly). Don't be afraid to ask questions, just be afraid of the time you will lose shuffling through worthless replies and pointless comments while never really knowing who is qualified to comment and if they are even right. For these things, I am sorry. Good observations about the slider and keep yourself hungry for knowledge! blincmagazine.com has some decent technical information, this is more of a social forum than anything else where honest technical discussion is rare. It is most familiar with ridiculous bickering, naysaying, bragging and meaningless posts like semi-psychotic babble about irrational fears and which cell phone is the best for BASE. good luck wading through the bullshit, better to consult a mentor/local experienced jumper than even post here. Enjoy there is always some kind of good laugh here. Premier Member IGPA 2009 IGPA Overall Champion WWTAD

I just want to let all of you know that I voted YES, and by the way I am going to jump an A tonight. Oh yeah, its pretty tall. Tom, I am glad that you support a sovereign technical BASE forum. Thanks again. Dirt Premier Member IGPA 2009 IGPA Overall Champion WWTAD

you could go to www.gravitypimps.com and see what might be one of the most amazing running exits in the history of the universe. It should tell you most of what you need to know. Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Just wondering if the aerial delivery laws apply to national forests the same as national parks? I couldn't produce anything with a simple search. Anyone know any details? Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Just tie the strings snug around your neck if not on the approach at least before exit if the hood concerns you. If it is real cold it will keep your neck warm, but it is easy to overheat this way if you do it on/before the approach. With the hood secured to your neck before you exit, there is no more chance of obstruction than with a fleece that rises high on you neck, I usually tie mine down right before I exit. I am yet to make a jump without a hoodie. If you really want core heat with less layering, go buy a vest at a thrift store. You can wear this under everything and it will keep you warmer than a hoodie. Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Thanks to all of you that posted. I truly do appreciate it and I think it is good for discussion. I have spoken with a few manufacturers as well and their first recommendation was always diluted Woolite dabbed rather than scrubbed. Also, they are stating what at least one of you said "Oil itself will not threaten the structural integrity of nylon parachute fabric, dirty used oil can." Having an engineering degree, I assumed this much (which I know may be a mistake) as they are both generated from petroleum and are generally minimally reactive in their purest form. Thank you to all who confirmed that to me. Now, the harsh chemical byproducts present in oil used in any type of internal combustion system will understandably harm the fabric as these left-over compounds are far from stable and pretty reactive. The loft that relined this canopy did mention the possibility of sewing machine oil coming into contact with the fabric and "staining" it. I cannot say whether or not this is the case as I don't know that I noticed the stains right away. That doesn't necessarily mean that they were not there. Here are the three most common answers that I received from manufacturers regarding cleaning oil based stains from zero-porosity fabric: 1. Diluted Woolite 2. Mineral Spirits 3. Rubbing Alcohol I think that the theory is to start gentle and then try more harsh cleaners. Of course after the fabric has been cleaned, it needs to be rinsed thoroughly with clean water per the manufacturers (and probably common sense). I have used mineral spirits in the past to remove some sap from the topskin of a zero porosity canopy and it worked well. That was only a surface issue though, no "setting" of a stain. Nice to see a thread where people are sharing honest technical information. Thanks again all, I think this will solve(nt) my problem Jeremy Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Will the oil really cause any true weakening? It is not soaked there are a few spots here and there some larger than others the largest is probably 4-5" in diameter and the concern is because it is on the top skin of the center cell near the bridle attachment point. Also, this happened while I was kiting the canopy in the grass to make sure that it was attached properly to the risers and I didn't notice until about a month later. I am speclating that oil based stains "set" pretty much right off the bat so the duration of time shouldn't make too much difference. Can anyone confirm that?

I have heard a little different but.... That number is for a fax machine, but thanks anyway. Jeremy Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Unfortunately, I got motor oil on a zero-p canopy that I have only 2 jumps on. I was wondering if anyone knows how I could get it out or if it is even worth getting out. I have oil on an F-111 canopy that I use in more critical environments and it does not bother me. But, I am unsure what the implications could be on zero-p fabric. Could I just use mineral spirits and the rinse it completely out? I did that for sap one time. Any riggers that have done this before, I would appreciate your input. Please try and limit the opinions and speculation. Thanks Jeremy Premier Member IGPA 2009 IGPA Overall Champion WWTAD

First off, I'm not trying to flame you, just prove a point. Two, that was totally disrespectful. I totally agree with and respect calvin19. I also agree that noone should get into rope jumping, as a climber i know the design specifications of your average 129.00 rope, usually around 5-7 UIAA falls, not quite enough to handle repeated factor 2 falls and extreme use. Also, I understand the complex nature of the tyrolean rig and how multidirectional the forces (stress and strain) are that result on a rope designed for unidirectional force. The beauty and wonder of mathmatics can result in critically high stresses, that may not be intuitively or visually evident. That shit will kill you! The gust of 109 mph was recorded at Kenosha pass which is about 45 miles from denver and more like 60 (57.4) from boulder. There was one, one gust of 97.9 mph recorded in boulder on MONDAY morning at the National Wind Technology Center, not Tuesday at 3:00 AM when this incident occurred. Yes the winds in the area were a pretty steady 50 mph on average during the morning on Monday. By the afternoon on monday though, the wind had already weakened considerably and was at 9 mph by 2145 Dec 5 and 14 mph at 545 on tuesday Dec 6 with very little change in barometric pressure over that time. Those are conditions in which I would likely BASE jump. The rest of the wind that evening was uneventful, the majority of the damage (not that there really was too much ultimately) occurred on monday morning. Yes there was a Piper that was flipped over and heavy equipment was used to shield the remaining aircraft at the airport. Just because there is a rumor in an internet forum that some kid was jumping from a crane in 100+ mph winds does not make it true. Did the incident happen? Sure. Does that give anyone the right to call someone (who for one happens to be dead and definitely not from suicide more like a mistake whether poor judgment or lack of knowledge it does not matter, it could happen to anyone even me) who has absolutely no affiliation with these forums at all a "dumb ass!!." You can do what you want, but in my opinion it is totally unacceptable. You too can find these simple facts by maybe doing a little research into the situation rather than just following rumors blindly. Hopefully you feel ultra confident knowing and making sure everyone else knows that you are less of a "dumb ass!!" than an 18 year old adventure seeking kid from boulder. Great karma, if you're lucky, it will roll with you throughout your base career. Oh yeah, I have absolutely no attachment to the deceased, I am just tired of reading flames directed to those who are unable or unwilling to defend themselves. My sincerest condolences are with Ryan Young's family, though I never knew any of you. It is never an enjoyable experience to lose someone you love to something they love. I will never blatantly desecrate someone else's reputation after a misfortunate event, who knows, maybe I'll be next? Has BASE taught you nothing about yourself, or is it just some kind of fun little game/hobby? I'm sure eventually you will have an experience that will put your own life into perspective, I just truly hope that isn't your last experience. Hey I agree with common sense, no disrespect for poor decision making, but don't forget to think!! Jeremy Premier Member IGPA 2009 IGPA Overall Champion WWTAD

Yeah, First one broke, the compass and altimeter both completely quit working. Thought it to be an anomaly so I took it back. The compass was off 120 degrees and couldn't be recalibrated by anyone, even the "techs" at the store where it was purchased. Even with readjustment of the altimeter for changing barometric pressure, the altimeter was almost always wrong shortly after adjustment. The second one broke as well in similar ways but to different magnitudes. I took it back and got a Suunto, which is great (as it can be). I think you get what you pay for with some of these trick electronic devices and they are only marginally reliable in my experience. Due to my negative experience, I recommend against High Gear to anyone, I wouldn't trust one. If they quit working for no reason (no abuse, no extreme condition exposure at all, they were almost brand new), what can really be said about their real-time accuracy and reliability? Just my opinion. Premier Member IGPA 2009 IGPA Overall Champion WWTAD
