Thanks for expanding the answer to my question into "after the paracast".
I was afraid that it wouldn't find much resonance but, boy, am I glad I asked now. I had no idea that Chris has made his own BOL observations and the account of Brendon's encounter in the 70s was just amazing. I would probably scare myself witless, but somehow I am envious because I've never seen anything like it.
I'm pretty convinced that BOLs are truely anomalous and not "just some lights" or even misinterpretations (although there are probably quite a few stories about "mysterious lights" were it is only headlights or airplanes). And the "intelligent behavior" which is sometimes reported at least in some cases is probably not just misinterpretation of erratic movements IMO.
Chris's description of lights moving between the trees which he'd seen in Colorado sounded just like an account I'd heard from an austrian witness, with the BOL lighting up the tree trunks, and avoiding them while seemingly meandering aimlessly around for approximately an hour. Ball lightning, piezoelectricity etc. would probably just hit the stems, maybe run along them for a second and then dissipate into the ground.
I guess they could still be called natural phenomena, but we'd probably have to redefine the boundaries of what we call "nature" first.
EDIT: for anyone who's interested, this is
Gerhard Gröschel's youtube channel. with some of his recorded material. As I said, they mostly seem to be BOLs (one seems to be an elongated or disc-like light form, changing color). I had posted the Wylatowo video before somewhere on this forum, where one light object seems to split into two and it got promptly dismissed as probably being wetness on the lense (must have been a strong wind to have the water run horizontally without any inclination of being bothered by gravity). Some of the videos have english explanations, but I'm afraid not all do. And the quality, as is normal with Youtube, is not the greatest.
Gröschel is not not one for "airy-fairy" paranormal explanations, (it's obvious that would prefer the ETH if anything), and I guess he's himself not too pleased that he doesn't get more nuts&bolts-like evidence, but in a true scientific spirit, he documents everything and checks for sources of misinterpretation and technical malfunctions before announcing anything as probably anomalous.
EDIT 2:
@Burnt State Did your chinese lantern / possible BOL flicker? The first time I saw a chinese lantern (we didn't even know about those back then), it took me about 30 seconds before I decided that the unsteady orangish-yellow light probably stemmed from a flame flickering in the wind. There were no sudden changes of direction, though, just a swift straight movement rather high up in the sky and no "zipping away", which made it easier to say it was something mundane.
For some reason, in your first retelling, I got the feeling that the light seemed to "streak away" into the distance (as seen from the side), whereas I'd say the flame just going out would just mean that the light would fade. Or was it headed exactly in the direction you were watching? I guess I didn't get that part.
All in all, don't you think we should sometimes get sceptical about our own "sceptic narrative"? Because I think the "narrative" here (and in other cases) could just as well be caused by a sort of "explaining-things-away-reflex".
