Triangular object with two lights in France

Summary

On July 30, 2010, a driver in the Isère region observed a triangular object flying lower than airplanes. The object had two lights on top and left a silvery, luminous trail in the sky. The witness heard no unusual noise, and the object quickly disappeared from view. There were no other witnesses or additional information. The gendarmerie report provided no further details, and the witness did not respond to multiple follow-up requests by mail and phone. Due to the lack of data, the case was classified as C by the GEIPAN.
