Val-d'Oise, France · 2010-07-01 · from the GEIPAN archive
On July 1, 2010, around midnight, a witness observes in the sky the particular "chevron" movement of a luminous point. The strangeness of this case lies solely in this chevron shape of the movement. The witness indicates a frequency of about 2 seconds for this chevron movement. By drawing a parallel with the long-exposure photo of an airliner (attached), where one sees an alternation of red and white lights along the axis of movement, lit every second, GEIPAN puts forward the hypothesis that this blinking could have been interpreted by the witness as a chevron movement. GEIPAN therefore classifies this case as "B": probable observation of an aircraft.
