As discussed in a previous post, there are reasons to suspect
that this fairly rare phenomenon is unrelated to what was
observed at O'Hare, not least of which is that supercooled water
should not be prevalant (if present at all) in low-altitude urban
atmosphere, due to the abundance of particulates providing
nucleation sites for crystallization.

Notice also that these "flash-freeze" holes are generally not
particularly "clean", since the newly-formed ice crystals are
also good light scatterers. I am not aware of any O'Hare witness
account that is specific about how stark the hole was, i.e., was
it literally a cookie-cutter hole inscribing pure blue sky? If
so, it would certainly seem to put additional constraints on the
underlying mechanism.
