I watched my first UFO from the town of Boulogne-Billancourt where I live, Saturday, 06/14/2014 between 1:10 ET 1:20 AM.I observed at all between 12 and 15 UFOs, all illuminated by a very bright light permanently and artificial orange color and flying in series of 2 or 3 UFOs with 3 or 4 separate series. The entire event during 10/12 mn.I watched the sky and the stars in the western direction from the balcony of my apartment when I saw the first orange light in the sky disappear (there was no moon in the sky that day and sky was clear but with a bit of moisture in the air). This light has appeared strange to me because it was not blinking, it had a yellow-orange color and there was no noise given the speed at which it was moving. This caught my attention. The light disappeared up in the air and speeding.I then scanned with a great attention the popular night sky in search of other UFOs. About 30 seconds later I saw 3 small orange dots appear that came from very far on my right (north) hovering about 8-10 miles away and between 500 m and 900 m in height. They came from the direction of North hovering almost vertically over "La Defense" then these points of light grew larger and became brilliant light orange color, quite similar to those I had seen previously, when it came over the "Suresnes" city. The orange lights are then directed to St. Cloud city and then to the park of St. Cloud and the Forest of Versailles. They went into the southbound then they accelerated soaring into the sky (40 ) to the southwest (above the Parc de St-Cloud). 3 lights flying together in formation and at the same speed. I have observed that these lights were not connected by the same structure, they are completely independent of each other. Speed ​​constant at first but seemed much faster than a plane or a helicopter (approximately 3 times the speed) and their speed is accelerated (between 6 and 8 times the normal speed of a plane before disappearing quickly) what makes me say that these are UFOs. The training was then separated and the UFO took slightly different directions from each other by speeding up and disappeared in 2/3 seconds in the atmosphere.After the passage of the first UFO, then I woke up my wife to be also witnessed the event.Three Other sets of 2/3 UFO were then reproduced with a similar scenario.I detected no noise, no breath, no reaction. No flickering, flashing lights, trail of condensation of water vapor (contrail) or otherwise.
