If I recall correctly, the venting of the Apollo LOX tank rupture was seen by
telescope by an amateur astronomer in Texas.
In any case, the "snow flakes" would quickly evaporate, leaving a volume of gas
going toward the Moon, or in orbit in the case of the F-9. Gas has a high
frontal area per unit mass.

Such events HAVE been reported and photographed in the past, and, as HenryS
stated, it IS a common event (in fact, it is uncommon not to do it, and is a
sign of a failure of the launcher or a failure to follow agreed-upon space
debris mitigation techniques). Although venting is very common, seeing it
depends on the observer being in darkness while the venting stage is in
sunlight, so that situation is less common, but not unheard of (more correctly,
not unseen).
