Loud Boom Heard + Flash of Light Seen in Montreal Last Evening, Was it a UFO?
I am always one for conspiracy theories when it comes to UFOs. Last evening in the Montreal area there was a a flash of light seen and a loud crashing boom heard at about 8 pm, but what was it? The crashing sound could also be heard in upstate New York. Was it a UFO? Was it a meteor breaking the sound barrier?
