The sling load system is used for multiple devices. ## Claims ### Claim 1 A system comprising: a plurality of stacked containers each comprising a coupling mechanism that is configured to: connect every pair of adjacent containers of said plurality of stacked containers when a top container of said pair supports the weight of a bottom container of said pair, and release the bottom container from the top container when the weight of the bottom container is supported by a platform. ### Claim 2 (depends on 1) The system according to claim 1, further comprising a sling configured to connect an uppermost container of said plurality of stacked containers to a host. ### Claim 3 (depends on 2) The system according to claim 2, wherein the host is an aircraft. ### Claim 4 (depends on 3) The system according to claim 3, wherein the aircraft is a VTOL (Vertical Takeoff and Landing) aircraft. ### Claim 5 (depends on 2) The system according to claim 2, wherein the host is a crane. ### Claim 6 (depends on 1) The system according to claim 1, wherein said coupling mechanism comprises a notch and a catch disposed at opposite vertical sides of each of said plurality of stacked containers, wherein the notch of one container and the catch of an adjacent container form together a clasp enabling the connection and the release. ### Claim 7 (depends on 6) The system according to claim 6, wherein: said catch is disposed on the upper side of each of said plurality of stacked containers; said notch is disposed on the lower side of each of said plurality of stacked containers; and said catch comprises a hook configured to prevent said notch from escaping a grasp of said catch when said clasp is coupled and the top container supports the weight of the bottom container. ### Claim 8 (depends on 7) The system according to claim 7, wherein said coupling mechanism further comprises, in each of said plurality of stacked containers: a transmission rod extending vertically along a side arm of the container; a first pin pivotally coupling an upper end of said transmission rod to said catch; and a second pin pivotally coupling said catch to the container, such that, when the weight of the bottom container rests on the platform, said transmission rod of the bottom container is lifted, pushing said catch of the bottom container via said first pin, thereby pivoting said catch of the bottom container around said first pin and releasing said notch of a container above the bottom container from the grasp of said catch of the bottom container. ### Claim 9 (depends on 1) The system according to claim 1, wherein each of said plurality of stacked containers is cuboid. ### Claim 10 (depends on 9) The system according to claim 9, wherein each of said plurality of stacked containers comprises a frame, four side walls, and a floor. ### Claim 11 (depends on 10) The system according to claim 10, wherein said frame is made of a stiff material. ### Claim 12 (depends on 10) The system according to claim 10, wherein the stiff material is selected from the group consisting of: steel, aluminum, and fiberglass. ### Claim 13 (depends on 1) The system according to claim 1, wherein each of said plurality of stacked containers is cylindrical.
