The force on charges we call radiation just goes where the re-radiation from
charges allows it to go. Someone else had an excellent clear post here a few
weeks ago about re-radiation (reflection) from earth in the Fresnel
(fre-nel) zone. The mechanisim in the ionosphere is no different. It is a
complex soup of charges that each become radiators, cancelling or enhancing
radiation in various directions and of course converting some radiation from
EM effects into energy that does not contribute to EM effects (heat).
"Always seek to propagate..." is a poor choice of words.

I'm impressed, but always like to reach such conclusions through
demonstration rather than proclamation
