That's so cool. The few minutes later is weird. Maybe it was something invisible nearby, or maybe the sound traveled to you, but a few minutes 180s*330m/s would be around 59Km away. If it was that far in the atmosphere it would have been huge, and maybe not even made a sound because the air would have been pretty thin that far away.

I hear that the crashes were shoot-downs or Trojan horse style gifts designed to lure us into co-operation with ETs who sly gave us tech far too advanced for us to figure out, then promised to slowly teach us how some of it works in exchange for whatever cooperation. There's lots of narrative and can be argued both ways, but without people seeing some hard data they believe, probably we'll have zero consensus.
