Hundreds claim they saw a large light, as well as heard one to two loud booms across Tucson Tuesday night.
KGUN 9 has received tons of calls and over 600 comments on our Facebook page from people across Tucson and Arizona. We even had a person in Flagstaff claim to see something suspicious.
Here's an account from our viewer Tony Kubrak: "My wife and I and my son were sitting in the house, and we felt this absolutely tremendous explosion, I mean, it shook the windows, it shook everything in the house. I stepped outside, and had to be no more than 3 minutes later after I hear all of this, and I see this tremendous, white, bright light in the western sky. And it was just...it was absolutely enormous, I couldn't believe it."
We also spoke to our Phoenix affiliate, KNXV. They said they have received the same types of calls from people in the Phoenix area.
Here are agencies who told us they have no idea what the booms and lights were: Pima County Sheriff's Department, Pinal County Sheriff's Department, Tucson Police, Southwest Gas, Tucson Electric Power, and the National Weather Service in Tucson.
