Eleven hours and 52 minutes.
That is how long the capsized Korean ferry sailed after departing from its port on Tuesday night, before it suddenly ran into problems.
Its 475 passengers expected to set off at 6:30 p.m. that night, but their departure is delayed two hours due to foggy weather skirting near the coastal area.
"We were told the thick fog would delay our departure time."
There are no indications of any trouble after the ferry hit open waters.
And around 10 p.m Tuesday, the ship passes by Palmido island, slipping through the Incheon coastal waters, heading south toward Jeju island.
By dawn, the Sewol ferry passes near waters off Mokpo near Jeollanam-do province.
8:30 in the morning.
Excited students wake up to thoughts of their field trip to Jeju.
Many either call or text family members about their whereabouts and to tell them they are safe.
But 20 minutes later, with just two hours to go before the ship is set to arrive at port, the ship comes to an abrupt stop and begins to capsize.
The students and others on board would be in Jeju right now if not for whatever caused the ship to sink.
Yet a majority of them remain missing at this hour, with a massive search-and-rescue operation underway to find them.
