Out of curiosity I decided to use the telemeter function of my Okean 3133 Final Edition chronograph to get the distance from the event to the camera.
I describe both the chronograph and the telemeter function in this video.
Well, it gave me a rather precise figure of 2 km 150 m.
That is the distance between the event (launch pad) and the camera.
So now you know.
CORRECTION (Sept 22, 2016): It just might be (IT IS!) that the telemeter scale on this watch is graduated not in kilometers but in nautical miles (after all, the watch is called OCEAN).
If so, the distance will be closer to 4 km (2 miles and 1.5 cable lengths).
P.S. The telemeter function on a mechanical chronograph works as follows.
The dial has a specially graduated scale called the Telemeter scale.
When you SEE an event (space x explosion) you push the chrono start button (pusher) when you HEAR the event you hit STOP, after which the chronograph hand (red central hand) shows you on the telemeter scale the distance to the event.
Of course it's based on the fact that the speeds of light and sound in the atmosphere are known as is the difference between them.
