Wild photos and videos from inside the Viking Sky cruise ship shows passengers and furniture sliding across rooms and tiles falls from the ceiling. Viking Sky issued a mayday Saturday after engine troubles and a harrowing encounter with rough waters and high winds. The ship tilted nearly 45 degrees. At least 20 of the 1,373 passengers and crews were injured. Nearly 450 passengers were airlifted to land by helicopters. A tug boat and two other vessels helped the ship reach the port on Sunday.
