Correct. If the Earth was condensed to a BH, each would follow
an elliptical orbit, with maximum altitude just about where they
(would have) started... Switzerland and New Zealand. They are
each accelerated into a circular orbit, for which they have
insufficient energy ot maintain, without the support of the
Earth.

I see the mouth moving, but can make no sense of the "sound". If
it is important, please try again.
