I was in a parked car with 2 friends in a yard on the suburbs. I was in the backseat listening the radio one Saturday at 1 or 2 o'clock (AM).My 2 friends who were sitted in the front seats start to say... "what is that...oh men...whats that light!!!". I got up and looked trough the glass... and i saw it.In front of us, at 3 or 4km starts a 700m mountain with a red light on his top, well, the UFO was 200 or 300meters above that light, it was like a "Little sun" , a red-orange glowing ball wich made mad turnings at incredible speed, one time... it seemed to fall with gravity acceleration but stoped instantly and continued makin turns.From hovering,the UFO flew more than 20cms in our perspective in less than 1 second, who means more than 10km in real distance,braking instantly and making other 10perspective cms in the opossite way, it did random turns during 2 minutes.At last, the ufo flew to our right (North direction) and we lose it, we get out from the car and ran to see it but we couldt target it no more.I am a veteran soldier of the Spanish Army, I was in afghanistan and in a lot of exercises , i used IR devices and marked zones to helis and planes, i know how seems the ordinary airplanes ... and it wasnt a plane or heli, it had imposible acceleration and braking.One friend who was sitted in the front was soldier too in the Spanish Air Force with beacon Works in the airstrip and hangars and he was impressed like me.We also know that the UFO WASNT above the mountain, we guess it was a lot of km behind the mountain at higer altitude, we were in Getxo heading west so we guess the UFO was above Cantabria, the neighbour province, we saw the UFO above the mountain cause the perspective...we guess.
