NASA investigating flash over Minnesota that made 'sonic boom'

"Beltrami County Emergency Management, which revealed that the sonic boom was too close to the ground to be a meteor - 'at least not ones that don’t cause regional devastation.'

DailyMail.com obtained an email from Juan Cabanela, a local physicist studying Monday's mysterious event, which states the timing of the boom suggests the object was, at least, no ordinary meteor. 'I still don’t know what it was,' Professor Cabanela shared in the email, 'but I was fairly confident it couldn’t be a meteor.' Aside from the local witnesses to the bright flash and the thunderous boom, three videos were obtained by Chris Muller, director of Beltrami County Emergency Management. 'If it was anything that would have been airborne, it should have been picked up by radars,' Muller said. 'We did check with the [National] Weather Service, and they didn't have anything on the radar. They also did not have any lightning detected.' 'So, we're actually leaning towards that this was something that was on or near the ground.'" MS
