  1. Of course you're right that it does,'t...especially if you are talking about group exits or freefly exits (always the one thing that the tunnel rats have problems with...well other than the whole canopy flight) BUT: I think for beginners it can actually help with that as well. The one thing it really does--if used correctly--is get your body used to the feeling of the air and how your body position affects your relative position in the air, and also simply to psychologically get used to that environment (which is a different component than psychologically getting used to "impending death" or the environment of the sky and "falling", which it doesn't do anything for.) Years back, I did my AFF, and then did not really want to continue jumping through the winter, so spent a lot of time in the tunnel. When I did my AFF, one of the main issues was the exit, and especially the fear on the exit, which did not help with control in that phase of the dive. When I did a lot of tunnel entries from the door, I realized that the exit from a turbine aircraft, really should feel exactly like entering the tunnel from the door on my belly: There is an existing airflow, and all I am doing is to slide my body belly-to-airflow into that stream, which then immediately "holds me up". This was completely different from how I previously approached exits from the aircraft, which I thought of as "jumping" or "falling down" (which isn't how they actually work.) So: When I came back to the sky, my exits were immediately different. All I had to do is imagine that the airstream from the tunnel wasn't coming straight from below, but from about 45 degrees down and forward. Then I could slide onto the wind, just as I did in the tunnel. Not only did that work from the first time I tried it, it also completely disappeared my fear of the exits: Even though the tunnel environment was so different in terms of the "death" and "falling" factor, my body immediately recognized the feeling of trusting the airflow and that simply made the fear disappear.
  2. I find it very rare that anything useful can be gleaned from videos shot by flyers that are not specifically focusing on the video aspect of their flying. Videos shot from POV by jumpers who are treating their camera as if it wasn't there, rarely show anything useful. I've pretty much given up wearing a camera when I'm not purposefully focusing on it as an aspect of my jump. This doesn't necessarily have to be "outside" video. It can be POV, but even then, it requires me being aware of the camera and the fact that I am, at lest in part, flying in order to get a specific shot or perspective of the jump. I can't imagine that others have much better results. (maybe those 360 degree cameras can be a little better in this regard--except I can't get used to their videos at all, as they do not show a perspective that seems real to me in any fashion...but then: I can't get used to videos in portrait format either and there is an entire generation that seems to have no problem with that! )
  3. Oh, one more advantage of the mount. Before exit, it's easy to pull the camera off to make sure it's on, and then stick it back on again quickly. With a top-mount there is always that nagging question: is it on?
  4. Here are some inside perspectives from belly group and coaching jumps and one freefly jump, showing the camera perspective. You can see how it's ok sometimes but can get low, if you're flying with your head down or are a bit low on the formation. But then again: Inside video on belly jumps is always of dubious quality, no matter the camera or mount:
  5. I love the convenience of it. My head mount got ripped off by some excited jumper yelling "dooooor" and slamming the door open--so at least this won't happen with this one. Videos are good when POV filming on a freefly jump, as well as when flying above a group as video flyer, but at least for my flying style, on a belly group jump, filmed from the inside perspective, you get a different view than top of the head. Even with the camera pointed as far up as it goes on my G3, I get a viewpoint that is a bit too low, showing more bellies than faces--but that may be a good thing, because it's teaching me to fly more with my chin up on belly formation, improving my view on the formation in general. Funny, about them being banned. In terms of safety they seem much better than the standard top of the helmet mounts--especially the default GoPro ones with the big thumb-screw. They pull straight off. I also like that they can be mounted without drilling any holes or sticking any tape on the helmet and I can use my helmet for head-down tunnel training, because I can keep the black tape on top of it, so it doesn't get eaten up by the net.
  6. I think that's what the original post is more about. It seems to be geared towards first time tandem students. The potential liability problems for a business that provides services to pregnant women that could potentially be later seen as the cause for any problems to the unborn child (no matter if the skydive actually had anything to do with it), make it understandable that they would simply say it isn't safe or recommended--even without much evidence. Why take the risk? (to the business?) For a licensed skydiver, it's different. They are not as likely to be able to sue the DZ, if they made the choice themselves, and especially if they checked with their doctor. It's the same as the age limitation: There is no reason a 16 year old couldn't safely do a tandem jump...but why take the risk as a business, given the possibility of lawsuits?
  7. This month's Parachutist has something on that--related to repeated hypoxia. Given that I jump in Colorado and we are above 17-18k MSL on almost every jump, the article makes it seem like we should be suffering serious cumulative long-term effects.
  8. From my own experience as a big flyer, I would add one more thing: I would not overdo it with the "slowing down". The problem is, that if you get used to constantly flying near the minimum fall rate you are capable of, you will develop a style that you will later have to unlearn, because it is not the most efficient and flexible style of flying, especially if you get into more competitive formation skydiving, such as 4-way or 8-way. Now, some of that may be unavoidable, and there will probably be multiple times, when you have to unlearn some things and update your flying style. Nevertheless I think it's best if you mostly try to fly somewhere near the middle of your range and, if anything, try to increase your range in BOTH directions--which, as others have pointed out, is best achieved in a tunnel: For example, if you are currently most comfortable flying at 74% speed in the tunnel, but can fly between 72% and 76%: Don't just try to get to 64%. Instead try to increase your range to be able to fly between 68% and 80%, etc. That way, when you DO fly with really slow fallers, you can match them, but you'll be aware that you are flying on the low end of your speed--rather than just unconsciously adopting an extra-slow flying style. Ultimately, in teams, the slower fallers will wear weights. The only way the faster fallers should probably adjust to the slower ones is by loosing weight! ...but for beginners, wearing weights is not a good idea, because of canopy loading--so don't ask them to do it...yet! Suits will definitely help. A little bit of extra fabric between the upper arms and body can greatly help. I got my first RW suit, by talking to Bev from BEV Suits, and 400 jumps later it still works great. tony suits is a bit more expensive and takes much longer to get, but everyone says they are absolutely excellent. Anyway, just wanted to add that.
  9. So, then what about all the Wingsuit proximity jumps that start out of a helicopter above a mountain range? Are they all illegal? There are tons of promotional RedBull videos of them. I cannot imagine that a large international company would associate themselves with patently illegal stuff? I assume therefore, that all of them are from outside the USA? If so, why would it be illegal in the USA but perfectly legal in most European countries? Given that Americans are constantly screaming that their country is the only one where real freedom exists, and how deplorable the "European nanny state" is, how could this be? Seriously though, does anyone know what went wrong historically or politically, that the US is so hostile to base jumping, while Europe is not? It seems to go against what the US claims to stand for. (Not that I want to jump out of an airplane with a BASE rig, but still)
  10. Well, I mean, I hate to say it, but the quote from the document (if correctly quoted) is a little bit problematic AND I think Wendy actually recognized this, which is why she changed it (to "many things"--indicating that it does not apply to everything, which the original quote somewhat seems to suggest) I do think there are some things that--if not having one single correct way--have certainly vastly MORE correct ways of doing things than other ways. Otherwise we are definitely back to teaching Noah's Ark side by side with evolution and consider them both as simply two different, but equally valid, ways of doing (or thinking about) things. This really cuts both political ways, as it enables the "post-truth" way of news reporting and political discourse (which is really more of a "pre-truth" way, in most cases) that has been so endemic on the right (but has its mirror in the extreme post-modern and "critical theory" thinking of the left) Just sayin...
  11. Yeah. It's kinda funny how Giuliani, Trump and all the other morons claim 'voter fraud' in front of the cameras. That they have proof and evidence that the election was fraudulent. Then, in front of a judge, where lying is a crime, they have no evidence. Old game: All the crazy right-wing "news" shows pretend that they are providing real news and every single time they get sued, they claim in court, that "it's just entertainment" and "no reasonable person would take us at our word". Shows what they really think about their intended audiences.
  12. Yes, I think that may be true and I would actually like this to be true, because wouldn't that leave the possibility open that something other than deterministic materialistic events, is having an influence on the physical world. This would at least leave the door open for how the realm of consciousness (or choice, if you will) CAN affect the physical world. I am just saying that generally deterministic materialistic atheists do NOT believe this is the case. Nor do most Physicists believe it has anything to do with consciousness or free will. (Although I recently talked to one in the field, who does think the two may be related) Even I am somewhat agnostic about this, and do not think that this feature of quantum mechanics necessarily has anything to do with consciousness or choice (nor does it need to in order to allow for consciousness to be a reality that is not completely determined by physical matter) It's also a matter of the definition of "real world". It used to be that most theoretical physicists were very interested in the philosophical implications of what they found. Physics was really meant to not only give us practical results but also help us understand our world and our place in it. Einstein was a prime example, and even Heisenberg was interested in this. However, modern Quantum Physics has gone away from this (it may have something to do with the difficulties of understanding their own theories, that eventually led to the Copenhagen Interpretation). Most modern quantum physicists like the saying: "shut up and calculate", meaning: don't worry about what this means and simply use the calculations to get extremely accurate and useful results that you can use to predict events and build machines, etc. So to them, the mathematical formulas are the "real world", our perceptions and even measurements to some extent, have become secondary (because they are indeterminate and "troublesome") I think that's a loss--but that's a different issue.
  13. But you can't know them, so you 100% can't. Yes. you can. completely. The wave function is known and describes the particles completely. It just doesn't give you simple location. That's not a problem though--except for our expectations. I haven't mentioned my worldview--at least not in any completeness--so yes, and no. I do not have any fixed worldview on this. I like some parts of the "Atheist" view, but I find inconsistencies with it. That's all I am pointing out. I probably find it a bit presumptuous to have a fixed worldview on this particular issue. So I am looking for parts of philosophies/worldviews that make sense, but trying to eliminate the parts that are not consistent. That's what this thread is about. I do lean towards certain ideas and I find others untenable (for example: a God imbued with human-like qualities that controls everything, or a world entirely devoid of anything but mechanistic externalities)--but beyond that, I think it makes no sense to have (and defend) a fixed view on something that clearly we have a very limited set of knowledge about. My personal experience led me through the study of physics (although again, to be honest: I did not complete my degree in it) as well as a period of 10 years of intense meditation and monk-like existence. Both explorations gave me some insights that I feel are relevant--yet none of it gave me a fixed worldview...if anything it made me drop much of what I had in that respect.
  14. Right, not physicists. I am talking about what I originally called "Atheists"--but since everyone is giving me crap about it, then called "reductionist materialists"--most of those--whatever you want to call them.
  15. I don't think it does contradict what I wrote: The Copenhagen Interpretation has three primary parts: The wave function is a complete description of a wave/particle. Any information that cannot be derived from the wave function does not exist. For example, a wave is spread over a broad region, therefore does not have a specific location. When a measurement of the wave/particle is made, its wave function collapses. In the case of momentum, a wave packet is made of many waves each with its own momentum value. Measurement reduced the wave packet to a single wave and a single momentum. If two properties are related by an uncertainty relation, no measurement can simultaneously determine both properties to a precision greater than the uncertainty relation allows. So, if we measure a wave/particles position, its momentum becomes uncertain. (source: http://abyss.uoregon.edu/~js/21st_century_science/lectures/lec15.html ) So, the very first sentence is "The wave function is a complete description...." and "Any information that cannot be derived from the wave function does not exist" So: The wave function is describing the "real world", even if it does not give us simple location, as we are used to. Also: even though it is the most commonly cited interpretation of quantum mechanics, the Copenhagen interpretation is just that, an interpretation. For example: (source: https://plato.stanford.edu/entries/qm-copenhagen/ ) Anyway, that stuff is fascinating, but I am not sure it is clear in which way this affects questions of determinism and consciousness--and in any way I do not believe that most reductionist materialists base their ideas on these concepts. Most still base their ideas on a traditional interpretation of classical physics, which they do believe to be deterministic.
