However, I think the evidence of ``The Corbomite Maneuver'', ``The Doomsday Machine'', ``The Ultimate Computer'', ``The Enterprise Incident'' and other episodes in which they were able to spring for fitting two ships in the same frame shows that, had they been able to afford fitting several ships firing at one another in the same picture then they would have, nominal distances and relative sizes notwithstanding.Thousands of miles. And TOS did it just fine. More tension in one of its battle scenes - which NEVER showed battling ships in the same frame - than in a dozen starships zipping around like racecars.
