Intercontinental Ballistic Missile Minecraft Concept

I had an idea for a flying machine that could be launched 200 blocks away from your target and still hit so I thought what if we launched two flying machines one diagonal vertical and one vertical the vertical one would be slow enough to hit the build limit at the same time as the vertical machine after they hit the build limit two horizontal flying machines would start flying in the same direction the back one slightly faster then the front one after a while they would hit into each other and then they could drop a bomb
