"There's only certain things that can make that fan reverse," Massey told "Early Show" co-anchor Harry Smith Wednesday. "We knew it had to be something big."
They were right. A .
Lambert, who's mined for Massey since 2001, suspects methane gas. "We know it's gassy coal," he said. "We know that when - you're gonna hit methane. You don't know where it comes from. Could come from a crack. Could come anywhere. All it takes is a spark. I can't see how they can point a finger at just anybody. It's just methane."
Does he feel Massey, whose safety record has come under scrutiny, is a safe operator?
"They treat me alright," Lambert replied. "There's no safe mines. I don't care where you go. You're not gonna find a safe mine. They could do whatever they want - make all the laws.
"When a man goes (into a mine), he knows that could be it. … You stick your head between two rocks to make a living, you know you're taking a chance. These 25 guys … they died for a cause. Every time you turn your lights on at home … you should think about them guys.
"Everybody overlooks West Virginia. They never think about coal. We need coal. We gotta have coal. Ya gotta have it. Gotta have it. Bottom line - gotta have it."
Lambert is holding out hope the missing are still alive: "Just keep hoping these other four guys - I hope they're just lost. I hope they find them. Keep hoping and praying."
