UFO in boomerang shape seen in France in 2017

Summary

On the early morning of March 1, 2017, a witness in Bron, France, observed an object in the sky described as a large boomerang-shaped craft, matte black in color, with white and flashing orange lights. The object appeared stationary and silent, surprising the witness enough to sit on the sofa to observe it. However, when he looked again, the aerial phenomenon had vanished. Only one testimony was collected, and the witness, frightened, provided few details and could not confirm whether the object moved or how it disappeared. The description of orange and white lights led investigators to consider the possibility of a celebration with lanterns, although the date was not typical for such an event. Additionally, no records of civil or military air traffic could explain the observation. Ultimately, the GEIPAN classified the case as "C" due to lack of information.
