Glad to hear you're OK. My wife's hand climber opened up because she didn't secure it properly and she fell backwards with her feet strapped to the platform.
Honestly don't know how she was able to swing her body upwards and cut the strap with her knife. Fell about ten feet and then crawled with her elbows up a steep clear cut about 600 yards back to the house. Neighbor found her in the middle of the road.
Tough girl.
