As rescuers take on the daunting task of finding survivors, family members of the missing passengers are pinning slim hopes on floundering air pockets in the capsized South Korean ferry.
They know the odds aren't in their favor, particularly after the entire ferry went underwater Friday. But they point to one especially miraculous tale of survival for their reason for not giving up.
In May 2013, a tug boat carrying a 12-person crew capsized off the coast of Nigeria. Two divers sent to recover the bodies assumed everyone aboard had died. After all, the boat was about 100 feet down under the Atlantic Ocean.
