My dad was in the Coast Guard and stationed at Port Canaveral on the cutter Point Charles during the later Apollo missions (Apollo 14-17, all four Skylab shots, and Apollo-Soyuz). They used to work at-sea security around Kennedy Space Center, maintaining an exclusion zone around the launch pad, mostly to keep idiot civilians on sail boats away from the launch area. But he said there were an awful lot of Russian "fishing trawlers" with no nets and a million antennas that they'd have to run off too.
He said on Apollo 17 he took a bunch of pictures of one of the "fishing trawlers" with his personal camera. When they got back to port the cutter was met by a bunch of men with dark suits and thin neckties who demanded the film in the camera. He refused, but relented when they mentioned words like "court martial" and "Leavenworth".
Good times.
