A model of safe landing capsule and ICBM multi war head transportation system for cluster type bomb attack by analysis of seed landing trajectory. Swietenia mahagoni (mahogany) seed has the uniqueness on its falling characteristics. At the time of falling, mahogany seed rotates in the axis center which is similar to the gyration of propeller towards its pivot point. The seeds look and behave like helicopter rotors. The gyration slows down the landing time whereby it is furthering the landing distance of the mahogany seeds. In this paper focused on this characteristic of the mahogany seed for real world application analysis and also the whole seed model application analysis also including some tests on the seeds.
