Holy crap, I can't believe they're able to offer commercial BASE jumping to untrained customers. There's no way anyone would sell them liability insurance is there?

Insurance for the jumper seems to not be a problem. I couldn't easily find out about liability insurance for the operator, but I'd imagine that it's possible for the right price.
