Yes, I've had a similar experience as that also. I have been encouraging him to get/wear one for a couple years now. I even forwarded him the story pertaining to this thread. I think it is slowly sinking in with him but I'm afraid he will need a close call for it to hit. And if so, I hope it is only a "near miss".Sad story for sure. I hope your brother has a change of heart.
I use a harness and dropped the bottom of a climber 2 years ago when I was about 12' up (and climbing). Even though I was harnessed and both top and bottom section of climber were tied together it was not a fun experience. It felt like 15 minutes as I got the platform back underneath me but in reality was probably 90 seconds.
