Object trailing orange over Avize

Summary

For about twenty minutes in May 1979, two people in Marne watched an object cross the sky from southeast to northwest at roughly 500 meters altitude. They described it as a flattened rugby ball leaving a vivid orange trail of varying length. One of the witnesses, a future pilot, could not identify it as any conventional craft. However, the exact time of the sighting was never recorded and no other witnesses came forward. Classified C by GEIPAN, the case lacks sufficient data for further analysis.
