Analysis of special class of free-flight circumlunar trajectories presented uses simplified model of motion in earth-moon system, based on sphere-of-action concept; emphasis is on launch from circular parking orbit, very close approach to moon, and re-entry into earth's atmosphere at shallow angle; some results of special computer program are presented in parametric form and for specific time period; comparison with machine integrated circumlunar trajectories is presented, and methods by which circumlunar trajectories may be generated are indicated.
