Hook knife and reserve

Good observations. Paradigm shift - use a metal handled knife.

Or two... you cut through one riser, the canopy does something funny and twists up catching your hand, and your drop the hook knife.

You can...!????? Sorry Wendy but with the ailerons or/and rudder being probably stuck, a supplementary weight and drag at the very end of the airplane making the weight and balance of the airplane possibly out of control. Having the whole tail ripped off if the reserve inflate and endangering the entire load of jumpers including the pilot and the person caught in the tail...what can possibly go worst....???? I am a jumper and a pilot and I speak here on behalf of both : a reserve caught in the tail of the airplane is the worst scenario.

Learn from others mistakes, you will never live long enough to make them all.

If the line over is located toward the middle of the canopy I guess you will have a symetrical configuration and the canopy will fly straight. If the line over is near the edge it can slipped away to get you a good canopy but most of the time it is at the 2/3rd and the canopy starts spinning the side of the line over is.

I have no doubt it is indeed doable, and on a BASE jump or on a reserve, you might as well give it a shot. If nothing else it will give you something to do. But experience has shown that it's not as easy as people think, especially on canopies smaller and less stable than BASE canopies.

It looks like we have gone two different directions in this thread...

Cuting away your reserve with your hook knife if it is deployed and wrapped around the tail...

And hook knifing your malfunctioning reserve that was damaged, but now clear of the trail.

In the Miami incident the reserve canopy was already freed from the tail but it was damadged.

If I was stuck on the trail I would spend the rest of my life trying to cut myself off! Hopefully the pilot and the rest of the load will be able to bail out!

Bilvon, please explain what canopies will not fly with "free" brake lines. Also expain how this is so. Not saying its false just not understanding the hows and whys.

>Bilvon, please explain what canopies will not fly with "free" brake lines.

I don't know which canopies they are. During two separate incidents at Bridge Day, a jumper released and let go of both toggles during a slider-down jump. The tail then folded upwards, greatly increasing the jumper's descent rate. One kept folding up and straightening. I don't think either jumper was injured as they landed in the water, and I don't know what canopies they were, since I saw one from above and one from the landing area (where we were being shooed away.)

A friend who's a BASE jumper also mentioned something that I had not really thought of before. Cutting a steering line is not the same as letting the toggle go. When the toggles are connected, the tail of the canopy is held to a maximum deflection. Even if there is "slack" in your steering lines they are always pulling on the tail. Cutting one line will release all that tension and let the tail on one side literally flap in the wind. After cutting one steering line (assuming you can do it at all) your canopy may not fly straight or even fly well, depending on many variables.

...
Based on talking with him, various other stories and my personal experiments with pre-planned breakaways including ones side and one riser breakaway I'm going to suggest that cutting 4 risers one at a time is FAR more difficult than people think.
...

Would be interested to hear more about that. A knife goes through anything under tension like butter, but without the tension it's a different story. I would therefore expect the first side (or at least the first of the 4 risers) to go quite easily, but with that release of drag/tension (as the now-only half-attached canopy becomes a very long, thin streamer), I expect the other side would be *much* more difficult. And that's aside from any additional loss of stability being added to the mix.

And as you say, at that point there's still 2 (maybe 3) risers left to saw through.

This shit scares the hell out of me.
