Christopher Cline, the billionaire coal tycoon best known for reviving Illinois’s mining industry and making a fortune doing it, died in a helicopter crash Thursday. Cline died in an accident off the coast of the Bahamas that also killed six other people, Brian Glasser, an attorney who represented Cline, said by telephone. He was the founder of St Louis, Missouri-based coal miner Foresight Energy, a joint venture with Robert Murray’s Murray Energy Corp.
