I've seen paragliding in Korea and have considered it. . . this story gives me pause. . . (I know even at home it's a top cause of broken ankles. . . ouch). . . do you remember or can you find out the name of the company that had this string of problems? In retrospect, would it be possible to check for holes/bad buckles?
I tried bunjee jumping in the late 80s in Boulder. . . out of a balloon. I checked (and they showed us all points of connection. Cord to balloon, cord to harness, harness to me) everything to my satisfaction, and being a climber I may have had more inclination to do this. The balloon was teathered so the height could be measured. The company made it a point to stress safety.
This is Korea. Regulations are clearly not the same, bribery (and skipping town when a lot of people die) is rampant, and even the regular use of seatbelts/child-seats is a relatively new phenomenon. Things are improving rapidly! Gotta love the descending life lines (so you or
your partner can escape a burning love motel!). . . anyway, go, look at the setup, ask friends etc if they've heard of any safety problems, post in appropriate places (like here!) . . . I like that KOTR is so safety focused, yet we do engage in climbing. . . we clip into some dodgy pro/anchors. . . use good judgement and common sense
That said, I will defintely look into paragliding accidents/reports/problems before I launch off a cliff here. I'd also be concerned because my Korean isn't that great, and something like diving (and presumably paragliding) might be better learned in English. . .
