It was a four metre gap (or so) and a four metre drop, with an additional 3-4 metre fall if they missed the gap. It was, in fact, the biggest jump I've seen anyone do, far bigger than Mincom, and it scared me a bit. What if they missed? Would I be liable? Serious injury or death was certain if they didn't make the gap, or slipped off the wall. I was definitely more scared than they were!
I was actually running through the mental checklist: Call the cops? Run? What would I say?
