Even military aircraft from the U.S. had joined the search for Indonesia's missing KRI Nanggala-402 submarine on Friday, as the hours counted down to 3:00 PM EDT — when Indonesian officials said the vessel would exhaust its oxygen supply.
While the search has yet to be called off, it is with deep regret that we observe the passing of this deadline. With it comes the dwindling likelihood that the submarine, along with its crew of 53, survived."
