Sure, if the geometry and ionization are right.
Normally you won't hear it on underdense pings.  But on overdense bursts, 
with enough stations on, not unusual.
The "footprint" that the returned signal covers is small and changes as the 
location of maximum reflection changes.  During the peaks of some of the 
major showers (primarily the Perseids of 8 or so years ago), many times on 
144.200 I heard stations about 1500 km away to the NE suddenly come in, 
followed after a few hundred miliseconds by stations somewhat closer, 
followed by still others, until the frequency was a mess of fluttery QRM!
