That's so sad. I did this too in Yangshuo a couple of years ago, and felt the balloonists were a little cavalier about things at times.
It was a totally amazing ride, but at one point our pilot got a little too low and we came close to a cliff face and brushed over some trees on the way up (they go up and down between the limestone outcrops). That was scary enough. It was still fantastic though.
When you land you have like steep mountain on one side, rice paddies on the other and traffic passing by underneath until the last second - crazy stuff.
