> ...the pre-flight planning requires simulation of the complete flight path from launch site to target. The resulting flight path plan as well as the algorithm for course adjustments based on various inputs is loaded by the programmers onto a ruggedized memory stick, which is then passed on to the launch location and inserted into the missile. Fascinating.
