UFO Sighting in Paço de Arcos, Lisbon on 2017-07-03 06:40:00 - I only saw lights, which i thought was a plane. what caught the attention was the red triangle around.
After my morning jog, gazed at the sea while doing the stretching exercises. on top of the horizon i noticed a light, which i thought was an airplane, i thought was flying very low. from one moment to the another, a triangular red light begins to revolve around the light that i thought was an airplane. just as it appeared, it disappeared.
