It rattled homes and the nerves of people living in Lafayette, but the questions about a late night boom linger long after it occurred.
The buzz Monday at the Lafayette Brewing Company and all around the city was about what happened the night before.
"It was very weird. Very weird," said Jennifer Russell.
"It was more of a solid thud, it wasn't so (explosion sound), it was more of a 'boom,' then nothing happened," said Jim Surface.
Around 11 p.m. Sunday, there was an explosion, or something like it.
"It was a sudden, 'Wow, it's there, it's loud' and then it's over. Almost as quickly as it started, it was done," Russell said.
The calls came pouring into 911.
"Yes. It's very weird," said Lafayette Police Lt. Brian Gossard.
Comment: Unfortunately, as this article shows, people still lack awareness about the real nature of the cosmic threat and how to interpret the signs.
