Silent but deadly

Also - silent but deadly (which is also an unintended American colloquial
fart description reference)

If you can’t hear it falling how do you avoid it?

Like the V-2?



Bailey! Did you even read the passage?
The visual equivalent of silent but deadly would be?

Because they are "only great invisibl[y] clashing" which does make some sound

Synesthetically, the comparison of the invisible clashing to V-2's unhearability almost works...
