Leviathan

The Leviathan is the famous "Sea King" helicopter that has appered on Grand Theft Auto: San Andreas. It is the second largest helicopter on the game, and has the ability to land on water. It is used on one mission with a crane attached at the bottom, that can move vehicles. Whether there is a way to obtain a regular helicopter with a magnet like this is unknown. Once completing that mission a Levhitian will spawn at Verdant Meadows; your private airstrip.
