I was entombed once for 6 long hours. It seemed like 6 years. There were no visible means of getting out either – we had just to wait. I was once right next to a cave-in when my fire boss was buried alive. As we were working and chatting a big stone twice as big as a trunk came tumbling down on my mate from overhead, doubling him like a jack-knife. It squeezed his face right down on the floor. God knows I wasn't strong enough to lift that rock alone, but by superhuman efforts I did. This gave him a chance to breathe and then I shouted. Some men 70 yards away heard me and came and got him out alive. A chap who worked beside me was killed along with 71 others at Udston, and all they could identify him with was his pin leg. I wasn't there that day.
