But that was later—Challenge to Earth, to Authority and Federated Nations, was made intentionally nasty. F.N. vessels were ordered to stay clear of Luna by ten diameters and not orbit at any distance under pain of being destroyed without warning. (No mention of how, since we could not.) Vessels of private registry would be permitted to land if a) permission was requested ahead of time with ballistic plan, b) a vessel thus cleared placed itself under Luna Ground Control (Mike’) at a distance of one hundred thousand kilometers while following approved trajectory, and c) was unarmed save for three hand guns permitted three officers. Last was to be confirmed by inspection on landing before anybody was allowed to leave ship and before ship was serviced with fuel and/or reaction mass; violation would mean confiscation of ship. No person allowed to land at Luna other than ship’s crew in connection with loading, unloading, or servicing save citizens of Terran countries who had recognized Free Luna. (Only Chad—and Chad had no ships. Prof expected some private vessels to be re-registered under Chad merchant flag.)
