They do not look shell-shocked or stunned despite a potentially harrowing 18 days inside a dank, dark cave followed by a risky rescue operation that was dubbed "Mission Impossible". A former Thai Navy SEAL died while helping install oxygen tanks in preparation for the extraction. Later Thai Navy SEALs posted clips from the painstaking rescue that was carried out in three phases ending yesterday. It showed divers in headlights and scuba-gear carrying out the boys on heavy-duty stretchers. Experts have warned of possible long-term trauma from their experience in Tham Luang but medical officials have issued a drumbeat of mostly positive news about their condition, saying they are eating normal food and even asking for chocolate.
