It's high single digits of seconds away. But I think your point still stands. Burke turns his head to look at the rocket, so you can't see his lips aren't moving. His voice-ove that includes "planets or peking" is surely an edit and yes, you can hear the rumble of a rocket (maybe not even the same rocket.)
However, I don't think people were praising this shot for it's audio editing. I wouldn't be surprised if Burke re-recorded it and they dubbed it over the video. I think they're saying this is an amazing shot because the timing seems to be pretty good... He points at the rocket and about a quarter or half of a second later it ignites. This comes at the end of a 10-ish second sequence. Pretty good timing. Unlike other shots in popular media up to this time it would have been difficult to try to do a second time (though I guess they could have tried again at the Voyager 1 launch a couple weeks later.)
> … when Itchy plays Scratchy's skeleton like a xylophone, he strikes that same rib twice in succession, yet he produces two clearly different tones. What are we, to believe that this is some sort of a magic xylophone?
The amount of sound creation in documentaries, particularly nature docus featuring long-lens shots of animals in the wild, is a whole 'nother domain of lying-to-tell-the-truth.
Odd Angry Shot... One scene in Gallipoli... Apocalypse Now and Big Red One do "funny" things with the sound... I'm not sure those two films trying to be accurate as much as they're toeing some fi formalist line.
If you dig around, you can find more examples, but I think you're right in that the vast majority of films take liberties with physics in the service of visual storytelling.
No. They don't lose points for using a film production technique that was in popular use at the time (and is still in use.) The reason people say this is a well timed shot has nothing to do with the voice-over at the end of the shot.
They say it's a great shot because Burke hits his mark at the beginning of the shot, then he progresses through the shot, hits his final mark and points within half a second of ignition. All while delivering dialog. (Props to the camera operator who tracked Burke and pulled focus at the appropriate time.)
And then I think there's the thematic element of the subject matter. What you don't get by watching the final shot in that episode was the emotional impact of the Voyager launches. The space program was, at the time, continuing on from the high of the moon landings. The Pioneer probes had returned black and white images from Jupiter and Saturn but the Voyagers were going to return more colour images. They were a RETURN to space, demonstrating that the pioneer mission wasn't a fluke and that, as a people, we were capable of doing great things.
And now, as a people, we bitch in online forums about voice-overs.
One does not, as you suggest, need to deduct any points for editing the sound of an impressive bit of writing, timing, presenting and camera work.
