WHAT HAPPENED
Well... not to pick on wingsuiters… but seriously folks, it’s like they TRY to find reasons to land off! We love them though and, to be fair, despite what went down here, this jumper made it pretty close to getting back to the dropzone. At break-off, this jumper appears to slow down, flare, deploy… and there’s a tension knot! (A photo of which could be used in a textbook on what malfunctions look like.) The jumper, after some delay, realizes that he’s not going to clear it, chops, takes a second, and deploys his reserve. After some frustrated yelling, he safely lands off.
WHY DID IT HAPPEN
Many Unpredictable Factors
Tension knots are one of those unpredictable malfunctions that sometimes just happen. Some canopies are more prone to them, and packing errors can cause them because improperly stowed lines can catch and grab onto one another, effectively cinching down as they’re drawn taut on opening.
Also, not untwisting your brake lines can sometimes lead to tension knots; under tension, twisted-up lines can fold up, locking onto themselves or other lines. One thing a rigger who viewed this video suggested is that during that initial snivel, some of those lines may have caught on one another.
HOW COULD IT BE PREVENTED
Diligent Packing Procedures
This really comes down to diligent packing procedures. Everything from making sure your lines are set down properly, your brake lines are untwisted, and you’re not throwing down your canopy and letting all that work you did flaking everything perfectly isn’t suddenly undone. At the end of the day though, sometimes it’s just bad luck, and that’s why it’s important to remember your emergency procedures.
ADDITIONAL NOTES
Don’t Delay, Cutaway; Don’t Delay, Pull Your Reserve!!!
So, this jumper was low already we think. At one point you can see the analog altimeter on his wrist, and he’s at about 2,500 feet when he unstows his brakes on his main. Then he gets that diving canopy, and then he chops, and then he takes a second before pulling reserve. That’s a lot of altitude getting burned up and, if he had an issue with his reserve, or had he not been jumping over a bunch of farmland, those altitude-eating delays could have resulted in some serious problems.

Bro needs to know that even a reserve canopy can be staged and flared.
Leaving one toggle unstowed while packing helps you avoid canopy collisions during opening. I call it the no track bob pack job.
Hahahaha.
😂
The downward dog.
Every time I see a good reserve I wanna give a shoutout to our riggers!!!! They are AWESOME!!!!!!!!
Love the ride to the landing! I haven't left terra-firma this year and living vicariously through these vids is good for the soul. Not that I would want the "Mal" that lead to this happening.... 🤕
There was a toggle instowed. Can be easily noticed in the slow motion portion of the video - the right hand side toggle. That line - and twist- probably caused the tension knot.
very nice tension knot, good job filming it
maybe scenario is not perfect, "Nooo!" should be before reserve opening for a greater suspense
Great to see this. After a cutaway I got one of these in my reserve last year. You can guess the rest.
You chopped it as well?
I spun to the ground, pulled down on the back risers to reduce the decent rate, and accepted what came next. In retrospect, I wish I had tried letting go of the rear risers a couple of times to see if the tension knots would drop out; I was under a large canopy.
1:16 he starts screaming " nooo" coz his reserve just got repacked.
Nice work. Spinning while deploying the reserve, but eh, it worked. Looks like he pulled at 3500, successfully chopped around 2400 or so, under a functioning reserve nice and high.
And he kept his handles.
Easy peasy. Just like it should be.
Except he forgot to flare. Oops.
@@toddwitt939he flared, ancient reserve has 0 flare, this guys my buddy
a tension knot in the front section? a quite unusual sight. The most outer A line went inbetween one of the more inner cascades of A and B Lines. I doubt you could fix this except maybe stalling the canopy which may or may not help you there.
I'm not sure ida chopped that. I would've at least tried to fix it for another 5 or 6 seconds, but that's me.
@@SEILLChe was flying a nitron 170, one of my buddies, he was only able to BARELY stabilize the flight by doing FULL left toggle and no right toggle
Question for the advanced skydivers (I am still quite new). Is this guy using a smaller canopy and can things like this happen much easier with smaller canopies? I did noticed the left toggle line was whack as well so certainly a pack job potentially. But with a regular intro sized canopy like a 200 does this type of stuff happen often? Of course a bad pack job can cause problems no matter the canopy size but as long as I take my time with a pack job everything should go well correct and good body position? I also see maybe I am wrong but the wing suited maybe deploying in a more downward position?
Either way a serious question, some of the comments below have answered some questions I have and I tend to over think safety as I would like to keep doing this as long as possible with little incidents but like whitewater kayaking swims do happen as canopy failures that require quick focused thinking to control! I am always learning!
Basically the bigger, more docile canopies are less likely to suffer these issues because they are larger, low performance canopies so everything happens much slower giving time to kick out line twists that could pull the blood out of your head and make you black out being spun round on a super high performance tiny swooping wing. The larger canopies generally have thicker linesets and the thicker the lines, the less likely they are to tension knot. Not entirely sure on the USPA regs but in the UK, if you are a new B license skydiver, the smallest canopy you can fly would be a 200 unless you are under 81Kg (roughly 165lbs) and the same is pretty much true for a 170 and the C license which is a really good idea as it prevents ego's from downsizing too quickly and then screwing everyone elses day over by injuring or killing themselves by trying to progress too quickly in the most dangerous aspect of the sport. Something the rest of the world should really take up too not just for safety but spending time under a bigger canopy learning how to properly fly it with coaching prevents building bad habits and makes for a better pilot as the wing size reduces. Also saves a lot of buying and selling kit .
"Body Position" is the standard packer response for any opening questions that skydivers have but fairly reasonably called. The key to remember with the packers is taht you're paying for a pack job, not an opening job. Also, assuming your system must be similar, here B license and above skydivers are responsible for the equipment they jump so if the packer packs you a mal and you cut away, that's on you for choosing to jump the pack job. Packing for yourself removes 1 random element but gives you a better understanding of the canopy and you can see that the key steps have been done which gives you more confidence in your equipment which helps alleviate some of that aircraft fear.
These are really good questions. if your local parachute club runs a safety day, they are really valuable as they provide an opportunity to discuss such situations with other skydivers and instructors without distractions. Buddy checks on flightline help this too. Again, it is mandatory for everyone on the load to be checked and signed for by another qualified skydiver before the load can get onto the plane which is an excellent way of casting a second set of eyes on the equipment for those rare times something might be missed and there is nothing wrong with asking for the same in locations where this is not mandatory cos it takes just 30 seconds and provides reassurance and, to this day, I have yet to hear a good reason to not do a flightline check. The wingsuiters will be moving around the sky so they need to fly a pattern that doers not encroach the airspace of the other skydivers on the load so they will typically fly a box pattern returning to a deployment location at the end of the skydive so they will typically be away from the jump run when they open. They can plan the flight to open upwind of the PLA to assist in getting back to the airfield because they are moving anyway.
Keep asking questions and avoid bypassing safety steps as you start to feel like you gain experience. I don't yet quite have my D license so I would still consider myself to be inexperienced because skydivers are inexperienced below 1000 jumps. It's the Dunning-Kruger effect that makes inexperienced C license jumpers think they are better/safer than they are. Outside of swooping, it is generally in the 200-500 jumps bracket that skydivers are most likely to have an incident because it feels like you're on top of your game, the C license thing feels bigger than it actually is and you start to gain invincibility from the jumps you have done, especially if you're getting away with something dangerous that you don't even know you are doing. The time and experience feels like it is a lot but the reality is that you are still learning and there's still a lot to learn when you get your C license that you don't yet know is even an issue. Stay humble and downplay your abilities and, while you won't sound like a sky god round the camp fire with that attitude, skydivers will respect your ability of you say you'll try to do it and half succeed rather than say you can nail it with the same outcome. Most of all, enjoy the constant hunt for progression that is skydiving!!
this seems to be flying well isnt it?
Is that a MUST to cut away in this situation?
You're kidding, right?
Yeah no, full left toggle and no right toggle is not a way to land a canopy, plus, tension knots are scary bc they can undo at any point; so if it came undone at 100 feet with fully left toggle, he would have surely died
Yet another square reserve not stood up.
Bring back rounds.
All of my reserve rides are on a round (Pioneer Super-22).@@vlnow
Any landing you can crawl away from...
Nice DZ, 800 outs in all directions
Good ole Rochester
My personal choice would have been to keep the main chute since the only issue was a mild tracking problem. Why take the risk the reserve chute doesn't deploy properly when you have open fields as far as the eye can see?
can tell you've never flown a canopy with a tension knot, possibly at all
Really? Just looking at this video, the canopy looks like it could fold at any time.
yeah i would agree but as airforceman said. never happened to me before so dont know how that feels
Not mild tracking, he already has shit canopy/altitude awareness. Imagine him trying to land it like that. He will kill himself and smash in the ground.
@@jasonkelley5394 Agreed. When he's in level flight, it has the I'm-losing-pressure rippling look of a stall.
Dude should have chopped way earlier... Looks like he chopped at 1,800 or so... Burned off over 2,000ft trying to fix something that AFF students know to chop from.
Why is it so hard to stand up a reserve 😅
Disclaimer: never flown a reserve
It's a canopy you've flown a handful of times if ever, and I belive for being a 7 cell with a flattish glide the flare isn't as powerful, it seems unlikely it will be the same to land as a typical main
@@41Extremo I knew guys that could stand up land a round canopy
@@natural9743 With a good number of jumps, maybe. But now imagine jumping a new canopy that handles pretty different for the first time, with all the adrenaline and emotions of a cutaway followed by an off landing going through you
@@41Extremo ok fair call
You simply need to flare properly. Practicing flaring while under reserve will def help, but require you to respect your hard deck. ;) Disclaimer: Flown two reserves and ended up landing both of them standing.
Looks like he landed hard. Be prepared to land hard when you are behind a row of trees (feet and knees together and look forward). You will accelerate in the wind shadow. Try to avoid landing right behind the trees and go further down wind from the trees (at least 10 times the height of the trees away from the trees and further in higher winds).
Delayed, Delayed, Delayed.
Be on top of your game…Do better 😒🤦🏾♂️
Any cutaway you walk away from is a good cutaway
This is fake news. Wingsuiters never land off.
Зачем от рабочего купола отцепился? Можно было интенсивным левым разворотом правое ухо расправить.

What's he whining about? That canopy was a piece of shit anyway! Lol.
