I wasn't at the scene at the time of the accident (so I won't comment on exactly what happened--I'll leave that to the leader), but I know the victims. The fall was from the second pitch of Yum Yum; at least 60ft, if not higher. Thankfully (somehow) he suffered only a few broken bones. He'll be laid up for a while, but should be no worse for the wear, all said and done. He was wearing a helmet, and it saved his life. The leader's hands were pretty torn up, but she'll be ok, as well.
They would like to sincerely thank everyone who helped out with the rescue. It was a huge team effort. Andrew the ranger was especially awesome and deserves a ton of credit for leading the rescue.
