I think he might have made aÂ* better landing under a rectangular chute.

Looks a little rough, but being fair, in the same compilation, there are several square canopy landings that look quite rough too.

I am surprised to see that. The Pioneer L-10 chutes (static line) I jumped with had quick-disconnects to prevent you from being dragged through the countryside like this fellow!
Do you think one could have 'flown' a rectangular chute out of such a dust-devil?
Anyhow, my next chute will not be a round one.

Apparently you *can* soar a round chute, if a thermal is lifting off.

None of my previous round parachutes had quick releases except for my
first, a surplus Navy parachute, which had Capewells.Â* All it takes to
collapse a round canopy is to reach up and grab just one suspension line
and pull it in as quickly as you can.Â* My wife and I each did it at a
training session with a 30 kt wind blowing.Â* We were tied to a pickup
truck with a 10 foot rope just in case.Â* We did fine, but one of the
students just couldn't get it and would have ended up in Texas were it
not for the rope!Â* It's not hard physically, since you're only pulling
on 1 line out of, 28.Â* I don't think it would be possible to collapse a
rectangular chute that way given the way the suspension lines are
configured.Â* I'll ask my rigger.Â* He's got a lot of experience.

HERE <https://www.youtube.com/watch?v=y45efUmZ4v4> is a good example of
a malfunction with a rectangular chute.Â* The jumper thinks that, if he'd
worked just a little harder, he could have cleared it.Â* I believe he
would have landed relatively safely, though not with control had he not
had the reserve.

And, to answer Jfitch, I'm pretty sure someone with a rectangular would
have had somewhat more control, but I don't think he'd have escaped a
beating, either.Â* I posted it to show just another thing that could go
wrong once you're dangling "safely" under your canopy, whichever type.Â*
It's a dangerous sport we're engaged in, but I'm not ready to give it up
yet.

Dan you can collapse a square by pulling any line. That said best plan if it is windy is to pull on one brake toggle, might have to windup some line. If you are going to collapse a square by pulling a suspension line, ones in the rear corners will work faster and easier than middle/front. Brakes will already be in your hand so it's going to be the best bet. Side note collapsing any parachute by pulling on a line in windy conditions without gloves on is going to leave a mark.

Thanks Gregg.

I was thinking exactly what you said after rereading my previous post
and I'll store that bit of information away.Â* During my training jumps,
the maximum wind allowed was, IIRC, 11 kts.Â* At that velocity, the chute
simply collapsed after landing.

I have been creamed under both rounds and squares. If it is merely wind and you know what you're doing, you're way better off with a square. That said, I tend to think that whatever kind of parachute he was using, that dust devil would have hosed him, and that walking away would be a matter of chance. An issue with squares is that they are prone to collapse in turbulence, and that can be very painful.
