Yeah, I figured as much. I didn't think an angle of incidence would be appropriate in terms of a human body in flight. I'm only familiar with that in regards to airfoils.

*** What do you mean by angle of incidence? Did you mean angle of attack? That bit confused me a little.

I've actually gotten out of the car and sat up on the window when my friend was driving. Stupid? Sure. But it legitimately felt like I was at the bottom of the hill and about to hit terminal. Oh, and I stick my arm out all the time.

First of all, that poem was extremely poignant and I thoroughly enjoyed it. You are a truly gifted writer. Secondly, I can identify with the first, second, fourth, and fifth things you said. I will say that standing in the middle of the landing area on a quiet day, listening to the canopies opening and swooping overhead, is pretty close to paradise.

I have to agree with you on this one. Someone swooped over the hanger one day and it literally sounded like a jet flying overhead. AMAZING.

Exactly! Man, these posts are amazing. So different, yet all related to the best sport on the planet. I love finding out what other people find to be particularly appealing or special. Make sure you never forget about the little things. They really do make a difference.

I've actually heard that. It took me a minute to process what it actually was and I had to check myself to make sure I wasn't imagining things.

That sounds like it would be prolific. I'm too young in the game to have experienced things like that but once I have the time to jump more...it's on.

I was cooking dinner a few minutes ago and naturally started thinking about how much I miss jumping (I'm in school again). In my melancholy reverie, I recalled the first time I actually heard canopies opening above me while I was standing on the ground. That distinct, almost ribbon-like sound, accompanied by the little dots of various colors that appear soon thereafter, never fails to put a smile on my face. I just think it's pretty awesome. Anyway, just wanted to share some thoughts.

Why thank you, sir. I'm going to have to find some time to read that whole thing and give it a go.

I'd like to begin by saying this is probably the coolest thread on this website. I love dreams and all aspects of the subconscious world, and it's refreshing to see that it is actually quite popular. I've had a few instances of gaining lucidity in a dream, but they always resulted in my waking. I remember one night I decided that I would learn the art of lucid dreaming, so I kept reminding myself that I was drifting off as I was lying in bed. At some point, I realized I was in that place between the conscious world and subconscious existence; the feeling was so strange and powerful that it shocked me awake. I think just being a passenger in dreams is equally as interesting, however, since the symbolism present in dreams can reach prolific depths. Attempting to interpret the myriad details of your own dreams or the dreams of others is actually quite fun.

That would make for one great sig line

THAT was what I was looking for. I just figured if you knowingly jump an aggressive, potentially "spinny" canopy you should at least be familiar with anti-G straining if everything goes Tango Uniform. And the suspension trauma, I'll have to look into that. I still don't quite understand the whole mechanics behind why I hanging harness would make that much of a difference in G-force distribution (besides the fact that you're body position is different).

Oh, I don't doubt that at all. And the HIC maneuver is an anti-G straining maneuver that pilots you to counteract the force of G on the body. Basically, you tense up your legs, butt, and torso while building up air pressure in your chest (taking a deep breath). It is named "HIC" because of the sound it makes when you forcibly hold the air in your chest and strain against the extra gravitational force. There are a lot of youtube videos that show pilots in centrifuges utilizing the move.

Hmm..that's quite interesting. I wonder if the guys flying sub-100 sq. ft. canopies have trained the HIC maneuver with any regularity. Oh, and I read the Chris Martin incident. Very crazy.

I was thinking it would be something along those lines. I guess I was wondering why there's such a discrepancy between hanging and sitting. I would venture to say that since gravity is already pulling your blood towards your feet, any additional force would simply amplify the force. It's interesting you mentioned aircraft because I spent some time in a centrifuge (some camp when I was younger). We got up to 5 Gs and, while I wouldn't say I was terribly comfortable, I was still aware and could lift my hands if I really put in some effort. That's also why I mentioned rapid onset as opposed to gradual. I know that rapid G-loading when not adequately braced (and even when prepared) can render even the most skilled pilots unconscious within seconds whereas gradual Gs tend to be comparatively more tolerable. Hopefully I get some more responses because this is a pretty interesting topic. Thanks for the reply

I was hoping someone could shed some light in this subject for me. I saw in another thread the mention of canopies that can cause GLOC, so I searched a bit but it seems like no one really had a definite answer. What I am curious about is the nature of the G-force that is experienced by a jumper under a rapidly spinning canopy. I have read that the small, highly-loaded ellipticals can spin up at a fantastic rate, and was wondering if anyone actually knew the maximum number of Gs that one could experience under such a violent malfunction? Some of the people in the threads mentioned numbers around 4-5 Gs, but these were really just guesses. I was looking to see if anyone had actually measured the true force. I understand that individual canopies have their idiosyncrasies, but I am interested to know if there is an average or any type of concrete correlation between canopy size/wing loading and the amount of Gs that one could possibly experience. The second aspect of my question concerns the physical experience of G-force when hanging from a harness. For anyone who has experienced such a malfunction, are the G-forces rapid in their onset or are they more gradual, topping out at a sustained value? Did you experience tunnel vision or the "curtain effect?" Being such a new jumper, I have absolutely no experience jumping even moderately-sized canopies; from the few videos I have seen, however, it seems as though there may be a split second before the canopy develops into a fully established spin. I'm sure I left out some other questions I have but I'm just intrigued to gain some insight from people who have actually been in such situations.

Thanks for the warm welcome.

Thanks Andy! It's actually pretty funny I was going over EPs today in my head on the way to class. My family says that I'm consumed by jumping...and they're absolutely right. But it's good to hear from you. Say hey to everyone for me.

Yoooo, I'm new here. Been visiting the forums for a long time as a guest and decided I should actually register once I got some jumps in. That, and I've been going through some pretty serious withdrawal since starting school again. As the title says, I recently (as in less than a month ago) got my A over at the Farm. Love that place and all the people, can't wait to get back whenever I have a break and make some jumps. Anyways, just wanted to say what's good and actually be able to talk to other individuals who care about jumping as much as I do.
