The final four boys and their soccer coach were successfully removed from a flooded cave in Thailand on Tuesday, capping a herculean international rescue effort that appeared bleak just days ago, ABC reports. “We’ve done what others thought was impossible,” declared the chief of a rescue mission to save a football team and their coach, stuck in a flooded Thai cave complex for more than two weeks, as quoted by Channel News Asia . The 12 boys and their football coach had been stranded in the complex since Jun 23. American space entrepreneur Elon Musk tweeted that he was in Thailand on Tuesday with a prototype mini-sub, at the flooded cave where five members of a youth football team remained trapped, according to Agence France-Presse. The Thai rescue effort has been assisted by experts from around the world.
