QuoteI often have weird/bad dreams about my canopy...a lot of times the only thing that comes out of the bag (with lines) is beach towel or an obese man's old ratty tshirt (seriously) - both very hard to land.
This reminds me of the scene from "Who framed Roger Rabbit", when he's falling off a building and asks Bugs Bunny for a "spare"... he hands him a bag and finds out its a spare Acme tire. LOL.
Mickey Mouse: "aww poor fella"
bugs bunny: "Yea, ain't I a stinker!"

You just found out one of the great truths of skydiving -- when the chips are down, you WILL do what you've been trained to do.
I'm a jumper. Even though I don't always have money for jumps, and may not ever own a rig again, I'll always be a jumper.
Hey Slappy,
Here's the thread about the pull vs squeeze method. It make COMPLETE sense because the canopy is fighting to get the linetwists out, and by puling them apart, you're really only countering what the canopy is trying to do.

Brian Germain introduced me to the grab the risers pull them straight and then push them together technique for line twists....not a major issue on a bit canopy since things appear to go slower for me than some of you guys with the huge wing loads.
What was the cause of the back lock? And if there a good rule of thumb for a new person to remember when packing so as to prevent such a problem? Other than keeping ones lines clean and organized?
Thank you.

Hey man,
I checked out my rig afterwards, couldn't find anything. I did another jump on it about an hour later and it worked as expected. I didn't change or "fix" anything prior to this next jump, not even replace an elastic.
I can only surmise the following happening:
1) A single line, or potentially a bunch got wrapped around a stow that hadn't unstowed yet, essentially locking it in. This cleared when the bag tumbled/spun enough to clear it.
or
2) Maybe a line got stuck inside of a grommet and again, cleared when it rotated enough to change the direction of pull. That being said, the grommets are pretty tight against the bag.
I'm sure there's a million other possibilities, but I'll never know now.

I've always wondered when my great idea will come to fruition...a robot camera that you toss out with you when you jump...follows you around the sky like a roomba. just for times like these when we wish we knew what had happened.

Quote..a robot camera that you toss out with you when you jump...follows you around the sky like a roomba.
Funny you say that:
Actually there is a vid out there of a test jumper for Daedalus who has a nasty spinning mal followed by a temporary main-reserve entanglement. His gopro got knocked off early in the sequence, and while it tumbles in freefall, on every revolution it keeps on picking up a glimpse of the jumper, who is descending under his mals at about the same speed as a freefalling gopro...

riggers:
what are the known posible causes for bag locks on main chutes, and how likly are they on reserve deployments assuming no main reserve entanglment? in refference to the main again, are they significantly less likly on a magnetic stowless d bag?
thank you!

for some reason im not able to edit my post, and reading it now it seems a bit impolite, so just posting to add that any knowledgeable info regarding my questions would be greatly appriciated, as is your time.
could just be my politness related ocd, if so, my polite apologies ;)

Hey out there,
one of the common issues of not known cause for a baglocks are colabsed PCs. There is not enough drag to strech the full line length then. This you can't check after the jump ...
have fun and be careful

My computer beat me at chess, It was no match for me at kickboxing....
Our collapsible pilot chutes need to be mantained on a regular basis.
Every time the kill line collapses the pc it generates heat which in turn causes the line to shrink (just a little on each jump). Over time and jumps this shrinkage causes the pc to be less effective because it's not fully inflated creating less drag.
This is often the cause for our slow deployments but because it happens so incrementally over time, we don't always notice it.
It's also often the culprate for our line twists. The longer it takes for our canopy to get out of the bag the more time for the bag to dance around and start a line twist.
It doesn't take much effort or cost for a rigger to replace your kill line on your pilot chute.
And while your thinking about it why don't you darken the green or blue color in your kill line window.
Remember it this way children............... just like in the bedroom..... shrinkage is never a good thing.

How is it a bag lock when it clearly opened???

I have to agree with what Sandy said, but would add that in this case, my guess is that you forgot to cock the pilot chute.
A good pilot chute will give enough drag to take you from "belly to earth" to pretty much upright.
If you had to look over your shoulder to see this, there was not the normal drag from the pilot chute.
When you brought your hands in and looked down at your handles, you went head down and accelerated. The additional speed is what finally gave the deflated pilot chute enough drag to open the bag.
I've had both a complete bag-lock after dumping my pilot chute to try to clear a horseshoe and the kind of delayed bag opening you describe, and the difference in what the pilot chute drag did to my body position was very obvious. In the second case, mine also opened just after I brought in my hands and was starting to look at handles.

This is the paradox of skydiving. We do something very dangerous, expose ourselves to a totally unnecesary risk, and then spend our time trying to make it safer.

Seriously? It didn't clearly open, it eventually opened. But initially it was a bag lock.

Quotehow likly are (baglocks) on reserve deployments assuming no main reserve entanglment?
Short and Sweet: Exceedingly unlikely.
The sport reserve deployment bag, called the freebag (because it is not attached to the parachute) typically has the lines stowed in two locking bights and the remainder of the line stowed within a pouch on the freebag. The locking bights are typically made using a single large loop of bungee-type elastic that is routed through a channel and each end sticks out through a grommet making a small loop.
The dynamic forces of even a low-speed deployment (ie, cutaway to reserve deployment) will be enough to extract the lines and strip the bag from the parachute.

It is a baglock when the canopy stays in the bag when you chop.

last weekend I had my first "near-mal"...dumped at ~4.5 (I'm a baby and like to open high) and didn't immediately feel an opening shock. within probably 2 seconds I had my hands on my handles - only to then feel my big, beautiful canopy slowly sniveling open above me. I'm still not sure what happened, but that is the closest I've been to a cutaway since I've been jumping, and I am just so proud of myself for being so prepared to cutaway. I know it sounds stupid, but I've always been so scared of having to deal with that, and always pretty uncertain what my actual reaction would be, no matter how much I pep talk myself on the ground. I often have weird/bad dreams about my canopy...a lot of times the only thing that comes out of the bag (with lines) is beach towel or an obese man's old ratty tshirt (seriously) - both very hard to land.
anyhew, long story short, thanks for the story and the accompanying lessons.
p.s. can you expound upon the squeezing vs. pulling? I've never heard this.
