I "saw" the Saturn V launch of Skylab in 1973 (just as a tourist - I
wasn't directly involved). One must put "saw" in quotes because the
experience is so much more than just seeing and hearing. TV can't
capture it. I seem to recall I was about a mile away, but that was
plenty close enough to be impressive. (I don't think they let tourists
that close any more).
One thing I recall was being able to hear/feel some of the sound as
distinct shocks, with relatively silent periods between. (Very short
silent periods - just barely detectable; perhaps it was even my
iimagination, but that's what it seemed like). Loud enough sounds can do
that, as the "speed of sound" isn't constant, and it shows up at large
amplitudes. The pressure waves will bunch together into a series of
shcks instead of smooth waves. Anyway, that was my after-the-fact
reconstructionn. In real time, there was just the experience; you had to
be there.
