    Why don't cannibals eat clowns? They taste funny. The world has just changed, and not for the better. Dave was one of the greats.

    I know a Barry Bichler. Different guy?
  3. 347 IIRC, but I was a SP-4 by the time I got it (I dropped out of High School and joined when I was 17).

    Paul Rafferty - post vibes here

    I was at the birthday party of my niece and nephew on Saturday, which always brings me back to the trip to the hospital to say goodbye to Paul on the day they were born. It was always a joy to run into Paul (and his fellow Knights) at dropzones throughout the circuit, over the years. He was a class act, and he is sorely missed. BSBD, Winsor
  5. Then print this out and tape it to your helmet or better yet, tape it right beside the lights by the door. In order for this to work the pilot must give you the groundspeed while on jumprun. As has been amply demonstrated, ground speed in and of itself has precisely nothing to do with freefall separation. One can have zero ground speed (jumping from a tethered balloon) and have excellent freefall separation, and one can have great ground speed (jumping from a free balloon) and have ZERO freefall separation. In practice this not as egregious a misconception as is the "45 degree rule," but it is still wrong. BSBD, Winsor

    Reserves Smaller than Main

    I hate it when so-called experienced jumpers trot out that BS argument, about PD canopies 'actually being more like a size larger'. By the same reasoning you could say that Icarus/Aerodyne/etc. is 'more like a size smaller'. [rant] Next time anyone tells you something like that, just smile and nod politely and go to someone qualified, like a rigger (which I'm not). Yes, there are different ways of measuring canopies. but unless you're a particularly high-talented competition swooper, you should view a 189 as a 189 and a 176 as a 176. Differences in size become more pronounced as the canopies get smaller. For instance, the flight characteristics between a 97 and a 120 of the same type are much different than between a 240 and a 190 of that same type. Aside from that, there should be no problem with a 176 as a reserve vs a 189 main. Though it is not all about size; the main is designed to have fun with, the reserve to get you home safely. [/rant] Agreed across the board, but I jump a smaller main than reserve unless the main is huge as well. I have landed reserves including 26' conical and 177 sf 5 cell (Swift), and have concluded that sizing the reserve is a matter of what I want over me if I'm incapacitated. Having your collarbone broken on exit can make using toggles effectively impossible, so you may want to keep your brakes stowed and steer by shifting in the saddle. Being unconscious for any reason - medical, injury, etc. - makes steering a non-issue. Having had an elbow to the nose in freefall that made seeing through all the blood problematic, it turns out that there are rather a few things that can make seeing where you are going difficult or impossible. You don't want to be under a reserve where being able to see clearly is necessary to avoid getting hurt. Regardless of what you jump as a main, a reserve is a whole different ball game, and should be treated as such. It's hard to look stylish in a trauma center. BSBD, Winsor

    Reserves Smaller than Main

    Having landed 26' conical and 177 sf 5 cell reserves, I want a nylon overcast when I pull silver. When I cut away my Icarus EXTreme 99, I landed under a Raven II 218. I have never been under reserve thinking "ah, I could have gone a size smaller..." BSBD, Winsor Wow. Your rig can really handle a reserve 2x the size of your main? No sweat. This one is a squareback Racer, 400/400 ci. It works great.

    Exit Separation Chart

    News flash: It's YOUR ass going out the door, not the person pushing the button. Stick around and you will see people come to grief by simply exiting when the green light comes on. As far as the 'rules' at one DZ or another, the physics do not change based on location. I have seen all too many DZs who relied on the aviation motto of "I'd rather be lucky than good" (look up the '45 degree rule'). If you pay attention, you will notice more near misses at places where the people in charge do not have a clue. Just because I have jumped at 100 or so DZs (16 in one day once) does not make me an expert in and of itself. However, I have a string of other credentials that do. BSBD, Winsor

    Exit Separation Chart

    I'm impressed. Somebody who gets it. Can you explain it to me? Sure. It's your basic frames of reference scenario. The reference planes of interest here are at exit altitude and at opening altitude, certainly not the surface. The exit interval times the aircraft's speed with regard to the airmass at opening altitude gives the effective separation at opening altitude. Since this tends to be less than the separation at exit altitude when flying into a headwind, and since the potential for overlap due to freefall drift and tracking increases as groups decend, the greatest likelihood of interference between groups occurs at opening altitude. Thus, the difference between wind speed at exit altitude and that at opening altitude provides a key parameter for evaluating freefall separation. What happens between opening altitude and the ground should be under canopy, which is a whole different can of worms. BSBD, Winsor

    Exit Separation Chart

    Without knowing what the wind speed and direction is at the deployment altitude, it is impossible to know what the acceptable exit separation time is. It's not the wind speed at the exit altitude (which translates to ground speed) that's important. It's the difference in the wind speed (and direction) between the two that dictates safe separation. I'm impressed. Somebody who gets it.

    Sandy Wambach RIP 7-19-98

    She took my slot in the formation after I got axed. I had refused to dive blindly at the formation to keep up with the guy ahead of me, and was thus like 3 seconds late; he got a foot print on his face for getting there on time (for real). Sandy is one of too many people who have vindicated the hard way my decision to chicken out. I have done enough really dangerous things that, by the time it scares me, it is likely a very bad idea. The tuition is steep, and it has already been paid in full. I got a hug from her the last time we said goodbye, and I wish she had been willing to get axed as well. BSBD, Winsor

    GoPros right off of student status?

    Maybe the sport, and human nature, has changed significantly since I was a neophyte, though I doubt it. The reality is that the distraction provided by having a camera on hand is the killer. I have lost too many friends who got preoccupied with things other than saving their life at the wrong time, and cameras have been the problem all too often. Sure, swooping makes other parts of the sport look safe by comparison, but playing Russian Roulette with a revolver, rather than an automatic, is not a fundamentally safe activity. Any professional cameraman (for news orgs, etc.) can tell you that, while the camera is running, their world exists through the viewfinder. Regardless of what is happening, one's perspective is geared toward getting the shot. Thus, you have footage of people being maimed or killed, well framed and in proper focus, when the cameraman did not stop to render aid. Similarly, I have watched footage showing the last things viewed by the person shooting camera, where they might have flared or whatever if they had not been preoccupied by getting the shot. Having made rather a few camera jumps over the years, ranging from 35mm and Super 8 to GoPro, I can attest to how much discipline is necessary to ignore the camera when things get dicey, and thus have footage of a couple of pretty hairy cutaways. Be advised that the dangers attendant upon increased complexity are not limited to cameras. Jumping flags, wingsuits, skyboards (remember them?) and the like increase the likelihood of an "interesting" outcome exponentially. As far as being a safety nazi goes, I would not dream of telling what to do. Hell, I'd be honored to be on your ash dive. BSBD, Winsor

    Paul Rafferty - post vibes here

    I had just left the hospital, where I went to say goodbye to Paul, when my cell phone rang. My brother said to make a beeline to another hospital where my sister had just given birth. Every year now, on the way to the twins' birthday party, I think of that short drive between the end of one life and the beginning of two others. Paul was a Mensch, and he is sorely missed. BSBD, Winsor
  15. Pretty much all of them do. The rub is if the jump is "intentional." If, of course, you were to wear a single parachute because you are simply terrified of flying, that would be entirely acceptable. If, in your highly agitated state you have a communications problem, where the pilot said "nice weather, eh?" but you thought he said "OH MY GOD, WE'RE GOING TO CRASH!," it would be perfectly understandable for you to jump immediately. When the pilot lands and says "has anyone seen my passenger? He got upset and jumped," nobody could blame him. "That parachute is for emergency use ONLY!" "Well, it was an emergency to me..."
