Theoretically, sure; a bolide could skip out of the atmosphere and return
on a second pass. Or at least I?ve been told this by people who?ve spent
more time on it than myself and I tend to believe them. But in that case,
?slow moving? is not an option. You would need a very fast-moving,
massive object that A) retains enough velocity to continue on after the
atmosphere slows it down, and B) has enough mass to survive the
atmospheric ablation. And I would expect it to be a mechanically tough
body, since even one fragmentation event would probably be the end of its
journey. You?d get something more like this:
So we?re back to a fast object again, certainly not something that someone
can video for more than three minutes like the guy did in Houston. I?m
certain the Houston event was an airplane.
