Holy Cow!
I was at 600 feet last night climbing a tower. GS Vision Velcro Rig, wearing the harness fully but loosly. I'm standing on a beam to rest and I hear my velcro pop, even though it's not tight and the velcro seemed fine, and a weight come off my back. The canopy fell out of my rig and there was about a 10 mph wind. I clipped my quickdraw caribineer immediately onto the tower to keep from being dragged off, with the other caribeener clipped into my chest strap. The canopy stayed small because of the locking stow at the tailpocket, pulled the stash bag out, clipped the stash bag to the tower, and reeled the canopy into it. Climbed back down with canopy in the stash bag. I feel humbled and very lucky and somewhat stupid.
