    Camera on the fly

    The dropzone you will be jumping at almost certainly will have experienced licenced skydiving photographers for the jump portion of your experience (but call and ask to be sure). The DZ may or may not let you bring your own outside photographer for photographing the jump portion (if you find someone qualified who would be willing to do this for you) so ask about that too if you decide to bring your own. The DZ should be fine allowing an outside photographer to shoot ground scenes, but call about that too to be sure, and so that they can prepare for it (DZ's don't normally allow spectators to be out in the landing area, or near the plane). Happy wedding!

    Scary stories from the old days?

    Bump. (Because it is a very entertaining thread)

    Monterey Skydive should be called out!

    This was one of the most discussed incidents here back in 2013. Here is the thread in the incident forum: And here is a parallel thread in the Safety and Training forum:

    DB Cooper

    I google searched for "parachute found in Amboy was not from Flight 305 as it was too large at 34-feet in diameter", and first link was this (which contains the exact phrase): https://themountainnewswa.net/2012/05/14/the-hunt-for-db-cooper-looking-for-the-amboy-chute/ Does this help?

    DB Cooper

    I don't know any of the details about what went on (I'm just a skydiver mildly interested in DB Cooper), so excuse me if what I say is so obviously contradicted by the known details. But I'm curious why you assume he didn't use his own rig? I certainly wouldn't trust a rig given to me by the authorities if I were in his shoes, particularly when jumping into unknown terrain at night. Even if I could assume they wouldn't jimmie it so I had a total malfunction, they might make the parachute small, or with other defects, that would ensure a rapid descent and a hard, injurious, landing. And I would have also thought about a tracking device being hidden inside. So why ask for parachutes? Could be because he assumed they'd put in a tracking device, and he would toss that out 50+ miles from where he actually exited so that any search would focus on where he wasn't. And/or use some or all of the rigs or reserves to do the final descent of some of the load he was carrying. (What did he exit with, and how much did it weigh?) And a night jump into unknown and gnarly terrain with tall trees? He could almost be assured he'd be hung up in the trees: maybe extra rigs were for rope/lines, etc to help extricate himself. Anyway, just some thoughts

    What counts as a freefall jump?

    Well, my Google foo must be weakening, as it apparently led me to the 2018 version. So I stand corrected: it is "freefall jumps" now in the SIM (2019 version).

    What counts as a freefall jump?

    Hmm, I didn't see that. I pulled up the online version of the SIM to check things, so if they did change the requirements, they haven't yet put it into the SIM.

    Canopy burn

    Ha! The latest issue of the Parachutist has a guy under a flaming canopy on the front cover! Apparently done at Z-Hills, so maybe ask them.

    What counts as a freefall jump?

    Actually, the USPA A License requirement is for "25 jumps", not "25 free fall jumps". The SIM defines a "jump" as a "skydive", which in turn is defined as "The descent of a person to the surface from an aircraft in flight when he or she uses or intends to use a parachute during all or part of that descent." So even if your parachute was deployed before you left the aircraft (only recommended if you are jumping from an hot air balloon), it would still count. (And even if you bounce with all handles in place, it is still a jump (although you would never remember that))

    The Deaf in AFF

    Google translate (in case anyone can help him, although someone probably should just point him to a German Skydiving site). Hello first good morning I am ayman. I also want to learn AFF how to go. Somehow I wanted to make course. I had parachuted jumps with me a couple of times but would rather jump alone. But I'm deaf, I do not know if it works or should not be. But I really want to make affic. Thanks would be nice if it works.

    Email from an attorney .

    OTHO, the defendant likely would be the DZ, who would know plenty of "friendly" experts they could call on, so they would be unlikely to be sending out cold-call emails to find someone. I think this is almost certainly from a potential plaintiff's attorney.
  12. Not in the US. In fact, in general patents are written to be as general as possible, with none of the detail that would allow you to copy a product using the concept embodied in the patent. That's on purpose._ This is false. In fact, if you can prove that a patent is insufficient for someone "skill in the art" to replicate the invention, you can have the patent invalidated. The whole theory behind patents is that the inventor discloses to the world how to practice the invention, and in return the government gives the inventor an exclusive right for a limited period of time. If the patent doesn't disclose the invention, then they don't get the exclusive rights to it.
  13. Actually, if it contains an element covered by a patent, you can't even make one for yourself. If it is not covered by a patent, as long as you didn't break the law getting the information to replicate it (like, say, stealing the instructions on how to make them from the WS mfg), than it is lawful. But I agree with what others have said: you probably won't find it worthwhile doing it.
  14. FWIW, I have a standard wings d-bag which has 4 closing bands (which go through the 4 grommets on the bag flap). I probably replace one of those 4 bands about every 6th jump or so (which means each individual band is lasting ~25 jumps).

    A better way out of line twist!

    It's been a long time since I had line twists on my canopy, but recently had an opening that twisted up nearly 3 full revolutions. I simply twisted my risers/lines to bring the twisted part down onto the risers, and that was sufficient to allow the canopy to get my body rotating to undo the twist. Thought I'd share the video. Does anyone know if USPA has added this technique to the SIM? https://www.youtube.com/watch?v=3YYaz0MriNI
  16. A youtube survey of skydiving mals will be massively unrepresentative. The fraction of video'd skydives by sport jumpers that get uploaded to Youtube is probably way less than 1% of those recorded, and the ones that do are more likely to be the interesting mals. Even then, the outcome is almost always a routine cutaway and reserve landing. Fear is useful if it motivates you to approach the sport with a mind to reduce the risk. IMO, you can likely lower the risk 10 fold from the "industry average" by how you approach the sport and by the decisions you make about what what gear you use, how you care for your gear, what activities you engage in, and what weather conditions will cause you to stand down. As a student, those decisions will be made for you, but hopefully you will come to recognize what are good practices when you are licensed.
  17. I'll guess that their theory is this: If the bridle is routed the "standard" way and the pin is oriented with a smilie-face, then when the bridle pulls on the pin and makes it "stand up", the end of the pin could (possibly) be pushing into the segment of the bridle that is still being held down with some force (due to a tight stow) above the pin, potentially piercing that segment. But if the pin is in the frownie-face orientation, the portion of the bridle that is below the pin and loop has already been cleared out of the way by the pull of the PC by the time the pin is forced to "stand up", and so less likely to pierce that portion of the bridle.

    Oregon DZ's with camping?

    I was in Oregon in June and jumped at Skydive Oregon a couple of days, and can't say enough positive things about the place. It's about 30 min south of Portland, on the west side of Molalla. http://skydiveoregon.com/ They have a blackhawk Caravan, which gets to altitude fast, and the views of the mountains are spectacular. The LZ is very large (~4000 ft long and ~500 ft wide), lift tickets were quite reasonable ($24 cash, $25 credit). And the people are friendly. They have a separate air conditioned (!) "clubhouse" for licensed jumpers with room to pack, comfortable couch, video screens, a kitchen and bathroom. And they allow camping. I highly recommend it.
  19. It would be a good idea to run it by your instructors, who can actually look at them. One thing you want to be sure you can do with any pair of goggles you use is to be able to see your cutaway and reserve handles when you are wearing them. It's not that important in skiing and snowboarding to be able to see your own chest area, but it is in skydiving. Put on your rig and and see if you can still see those when you have those goggles on. If you want something inexpensive that works really well, consider a pair of these: http://www.chutingstar.com/skydive/sky-eyes-goggles

    Forum Descriptions

    Funny you should ask that! I just today discovered that ability. Just below the blue menu bar you will see 4 links: "Search Settings Who's Online Rules " Click on "settings" and about halfway down the list there will be the "Forum Descriptions" option. You can do Full, Short, or None. Then click "Change Settings" button on the bottom right to activate.

    Why not use Vigil on student mode?

    Why not just program in an "altitude correction" to raise the trigger point however much you like? Unlike the pre-2013 Cypres (at least those without the newer firmware), the Vigil will keep using it until you manually change it back. This way you can stay in "pro" mode and not risk a AAD fire due to radical canopy maneuvers.
  23. How about a concise write up with all the relevant details? I'm not interested in watching a 12 minute docudrama just to determine if your accusations have any merit.

    dz use of Facebook and Twitter

    Just my person opinion of what twitter could/should be used for, and what not to use it for: Don't use it for: - general advertising of basic information. I know where you are and your usual operation hours, so I don't need to be reminded/told that. And I already know how much fun it is, so no need to remind me of that. Use it for information that I would be highly likely to want to know, but probably won't unless you tweet me. Things like: - "although weather/winds might look iffy where you are, it's fine here and we are flying loads with no restrictions." - "weather/winds sucks out here (or plane has mechanical issues): we've shut down for the rest of the day (or need C license or above to jump)" - "we will be open and flying on [a specific weekday normally closed]." - Low cloud ceiling, but we are running hop-n-pop loads. It would be acceptable to send out a one time (or once a week at most) reminder of an up coming special event. (Canopy course, ratings course, boogie, informal competition, etc)

    AFF1- Rode the plane down :(

    Unfortunately that is not possible. Just like it is not possile to have zero doubts that the guy driving towards you in the opposite lane isn't going to veer into your lane and cause a headon as you drive down the highway. All you can do is evaluate the statistical likelihood and either accept the risk or not. I've never heard of an AFF student falling out of their gear. For that matter, I've never heard of any skydiver falling out of gear that was otherwise properly secured (chest strap on, legs in the the leg straps). The risk must certainly be vastly less than 1 in 10 million. For this particular scenario, I'd venture the risk is less than the risk you took just driving to the DZ. There are things to "worry" about in skydiving, but on the scale of things, IMO this one is pretty near the bottom of things I could conceive of.
