FYI:  Rodney asked about the canopy, so I snapped a couple pictures and put
them in the NSL-4 group:

http://www.flickr.com/photos/cpgorski/6954035100/in/photostream#/phot...

To be honest, though it was tangled up in some pretty rotten latex, the
parachute itself is in surprisingly good shape.  It's a little bugbitten,
kind of sunbleached, has a couple tears, and a few spots of what's probably
some sort of mold... but generally intact, and I would expect the tears
could be mended.

I am not sure if I trust reusing it without testing, though.  Anybody want
to guess how to do that?

From the photo, it looks in great shape to me - we really don't care
about the cosmetics of bleaching, mold, etc.  I suggest we just try
hand washing it first to make it look better and get some of the crap
off of it, and then give a good yank to see if the shroud lines seem
firmly attached still.

If we can get one guy to hold the loop at the top and another to grab
the shroud lines and yank a couple of times and we don't hear any
further tears or cracking due to old nylon, I say it is good for a
launch.

Remember the guy that sold it to us told me that we could just go with
a streamer at the weight we are launching and that a parachute is
technically not even needed. So at worst, it acts like a streamer.

However, if you want a functional test, attach a couple pound weight
to it and drop it off a bridge somewhere (please not over I40, but
surely there is a place it can be dropped that will not endanger
traffic below). Personally, if the tug-test works and the material
seems supple enough, I would be willing to go with it.

That's probably a good approach in general, Rodney.

Just a couple of details:  I do want to address the mold, but only so it
doesn't get worse; the bleaching only concerns me inasmuch as it might have
weakened the fibers (though to be honest, it has been nice being able to
look for blaze orange in the tree line); and I'd like to try to figure out
how to patch the holes just so they don't get worse.

But I had forgotten he had suggested a streamer might be okay.

If anybody has a favorite non-chlorine mold remover, I am all ears...
Will try and test the chute shortly thereafter  in some way that doesn't
involve the 440 overpass near here!
