Gemini 7 said bogey on the tape
NASA, Low Earth Orbit, 1965.
The bogey line is real, and that is why the transcript is famous. The surrounding exchange matters because the crew also discusses booster-related objects. The quote is striking, but it should not be lifted out of mission context.
From the file
Borman reported 'a bogey at ten o'clock high.' Houston asked whether it was the booster or a natural sighting, and Borman replied that they also had the booster in sight.
The same exchange also includes many small particles going by, which is why the line should be read inside the full tape context.
