Two huge fireballs with blue tails. The sound was a rumbling roar.A hot summer night (early morning), nine months pregnant, my husband and I were out riding around because I couldn't sleep. We were stopped at an intersection just outside the city limits towards St. Charles at approximately 3-4 am when we heard a roar and looked up to watch two huge BRIGHT fireballs with blue triangle "tails" go over our heads and disappear behind the tree line. My son was born exactly one week later with the nail missing off of his right index finger.
