Summary
On the evening of April 13, 1958, a driver near Hamilton, Ontario, Canada saw a brilliant object light up the sky as he was traveling at 50 miles per hour. The object was blue-white in color and left a white smoke trail behind it. It moved in a straight line across the sky, visible for only a few seconds, and burned with enough intensity that the witness said the surrounding area lit up as bright as day.
The witness reported his sighting to the U.S. Naval Research Laboratory in May 1958. A Naval Research Laboratory official replied that while the observer might have seen a meteor, the laboratory had confirmed that the Soviet satellite Sputnik 2 had re-entered Earth's atmosphere and broken apart on April 13, 1958, the same day as the sighting.
The Air Force's Air Technical Intelligence Center reviewed the case and concluded that the object had all the typical characteristics of a bolide, or extremely bright meteor. The center noted that the witness's detailed description, particularly the "red glowing space" at the head of the object and the fact that the area around him lit up "bright as day," were classic signs of a true fireball. The center also observed that a large number of similar bolides had been reported throughout the United States during the nine months prior to this sighting. The Air Force classified this case as an astronomical phenomenon.
