Green meteor sighted in Colorado Springs and Denver

Summary

A green meteor with an orange trail was seen by three observers in Colorado on December 11, 1955. The object, moving northwest, was described as much brighter than jet exhaust. The sighting lasted between 3 and 5 seconds, and a USAF captain identified it clearly as a meteor. Although it could have initially been mistaken for a balloon, aircraft, or astronomical phenomenon, the report concludes it was a meteor. No photos were taken, but the description matched among the three witnesses.
