One night in july 2011 in the town of stettler alberta, close to 11 or midnight, i was leaving my friends apartment and as i was getting in my car, i looked up at the apartment building in front of me and witnessed what looked like a large green ball of fire streaking across the sky. the object looked quite low, couldn't have been much more than 100ft. from where i was, the object looked to be nearly the size of a snowplow, or other large piece of machinery. the object had no defined shape as it appeared like a ball of fire. at the time, i thought it was a meteor, so i tried to find where it landed. i found no evidence of where it landed, and there were no reports in the news of meteors afterwords. it wasn't until the spring of this year (2017) that i read several stories about green fireball ufo's dating back to the 1930's, it was at this time that i realized what i actually saw.
