100 chimneys drilled into mountain to reach boys in Thai cave
Over 100 chimneys are being drilled into a mountainside to rescue the 12-member teenage football team and their coach trapped inside a cave in Thailand. The chimneys may help rescue them from above if the cave's underground chambers get flooded. "Some chimneys are as deep as 400 metres... but they still cannot find their location," said the mission's head.
