[meteorite-list] Atmospheric ablation marks on Tektites?

Hi Group!
While reading through another Meteorite-related
message board on the WWW, I ran across a statement by
an IMCA member that puzzles me somewhat. A discussion
about Libyan Desert Glass was ongoing, and we were
sharing photos of our LDG specimens. (and I showed
off my new 9+ gram piece of dark-veined glass from
Michael Farmer - thanks Mike!)
So the guy says :
"This is one of my favorites and is fully oriented
with regmaglypts (yes, tektite impactites can have
atmospheric ablation patterns too)."
Ok, here is my confusion - I was under the impression
that tektites were formed on impact - on Earth. So,
doesn't this mean they cannot have atmospheric
ablation patterns? Assuming the tektite never passed
through the atmosphere, I don't see how this is
possible.
I have seen tektites with features that resemble
regmaglypts and orientation, but this is just chance
occurence, right?
Or do I need to be schooled here?
Thanks in advance!
