Black triangular object briefly sighted in Pont-sur-Yonne

Summary

In November 2008, a motorist in the Yonne area saw a black triangular object with two white lights at two of its vertices. It passed slowly over a span of five to ten seconds. Although a low-flying aircraft was considered, the location and description did not fit that explanation. The sighting was deemed low-strangeness due to the object's slow movement and light colour. Its consistency was rated weak, given the very short duration and the fact that the witness was driving at the time.
