2/ The ransom could be put into a container such as an inflatable ball and dropped by a plane or an helicopter on-board of the ship held by the SHT, using a parachute guided by a Global Positioning System. It is a more accurate and safer way to deliver the ransom, as it makes it more difficult to be robbed by other SHT but it's very expensive and not all companies have the capabilities to air-drop. The plane will fly three times over the vessel: the first time to be recognised, the second to check that the entire crew is on deck and the third time to finally drop the money.
