The other fatality in the Hopping system was on 2 July 1992 to Stephen Goodwin of Ripley, aged 23. A novice caver, he dislodged rocks when crawling through a narrow crevice and he was crushed. There was also a 12 year old kid killed in Fluor Spar Cavern when it was a show cave - the only known fatality to a tourist in any of the local show caves. He fell down a shallow shaft. No other mine system has such a terrible record of accidents to visitors.
I nearly got killed when surveying the system in 1970. I stood on top of a massive slab of rock at the top of a 20 ft slope down to the west end of Chaos Cavern. The slab, which weighed many tons, promptly slid down the slope. Not being Indiana Jones, I promptly fell off and got a bad cut on my head. But at least I was able to stagger out of the mine unaided (I was by myself at the time). As Trevor Ford aptly remarked, the Hopping System is a landslide in slow motion.
