                      Full 
                        Description of event/sighting: Background: I am an airline 
                        pilot (now retired) and I am also a qualified meteorologist 
                        and air traffic controller. I consider myself an excellent 
                        aircraft observer. A group of us were returning from flight 
                        simulator training in Rio de Janeiro on the road to Sao 
                        Paulo, Brazil.
                      We 
                        departed Rio late at night and drove along the main highway 
                        and at about 3:15 I was sleeping in the rear of the car 
                        which was traveling at high speed. The car was being driven 
                        by a local chauffeur and inside it was me, a senior airline 
                        captain at the time, an older flight engineer from the 
                        U.S. and my girlfriend who was a flight attendant and 
                        a pilot also. I was awakened by my girlfriend who pointed 
                        out a light in the sky which had been following us for 
                        a while, according to her. It was a bright red light in 
                        the sky and my first impression was that it was a radio 
                        antenna obstacle light high on a mountain. However we 
                        were traveling fast on a flat area and there were no mountains 
                        around and the light was keeping up with us. (Initially 
                        the light was at our 7 o'clock position on the left side 
                        of the car and then advanced to a 9 o'clock position) 
                        The light was moving erratically in a side ways and up 
                        and down motion but keeping its relative position to us, 
                        impossible for a stationary object. I thought of a helicopter 
                        flying out there, but there were no position lights or 
                        strobe visible and the light was moving in a very odd 
                        way for a helicopter. I am a helicopter pilot as well. 
                        The lights started to change from red to yellow to white, 
                        green and even blue. The lights were of changing intensity 
                        and reminded me of a dance room rotating light sphere 
                        or "disco ball."
                      This 
                        continued for at least five more minutes and we slowed 
                        down from 80-90 miles per hour to 40 and the light kept 
                        its relative position to us. Traffic on the highway was 
                        light but we reached a point where there was a bus, two 
                        or three trucks and several cars parked on the side of 
                        the road and people were outside of their vehicles watching 
                        the object in the sky. It was a clear but dark night with 
                        no moon, there was a cloud cover but it was high probably 
                        over 10,000 feet and apparently the object was initially 
                        flying at 3-4000 feet and a mile away from us. I asked 
                        the driver to pull to the side of the road and I came 
                        out of the car, followed by my girlfriend. The object 
                        was now descending and at a much lower altitude and closer. 
                        After a few minutes it was real low and hovering to the 
                        south side of the highway. The top lights were dimmed 
                        and the object was hovering but moving closer to our position.
                      I 
                        could not hear any sound and the lights were now dimmed 
                        but still changing colors and I could see the shape of 
                        the object and it was the familiar "flying saucer" 
                        dome shaped object. I walked two hundred feet on the side 
                        of the road towards the object which was hovering low, 
                        no sound came from it and the night was absolutely still 
                        except for an occasional vehicle passing down the road. 
                        There were several vehicles stopped on the side of the 
                        road further down and I walked back to the car quickly 
                        to get a camera.
                      We 
                        had an excellent professional Nikon camera with us. I 
                        opened the trunk to get the camera but we had taken many 
                        pictures in Rio and we had no film left. My girlfriend 
                        joined me and we walked back towards the object which 
                        was floating three or four hundred feet away from us, 
                        dimly lit now and probably at less than two hundred feet 
                        above the ground.
                      She 
                        stood back frightened by the sight but I was not afraid 
                        and walked quite close to the object maybe within two 
                        hundred feet. I actually crossed the dangerous highway 
                        to get a closer look. I walked into some grassy area until 
                        I was stopped by a barbed wire fence. At this point, my 
                        closest approach to the object I was probably two hundred 
                        feet away. There were a few dim lights on the edge of 
                        the object which pulsed slowly every few seconds, the 
                        lights looked square and they grew bigger when the brightness 
                        increased and smaller when they dimmed.
                      The 
                        object was not illuminated but the bottom emitted some 
                        kind of bluish vapor and when I got the closest to the 
                        object, I felt like a soft breeze was blowing into my 
                        short hair, though it was not windy at the time. It felt 
                        like an electrical charge was coming out of the object 
                        which moved slowly with a rocking motion not unlike that 
                        of a boat going through small waves. My girlfriend had 
                        walked back to the car and was standing behind the car. 
                        Even though the object was not lit other than the small 
                        lights pulsating on the edge, I could see its outline 
                        and its top clearly. In the darkness, the color looked 
                        like a reddish gray. The object was quite large and I 
                        estimated it to be at least 70 feet in diameter and about 
                        30 feet high. It was just hovering in the air at about 
                        120-150 feet high.
                      Some 
                        of the other spectators, probably a truck driver, shone 
                        a powerful spot light on the object and there were a couple 
                        of flashes of light, maybe someone using a camera flash. 
                        The second group of people was quite distant probably 
                        over 800 feet.
                      Shortly 
                        after the spot light illuminated the object, which looked 
                        metallic gray, not unlike the color of an aircraft when 
                        illuminated, the object started to move more noticeably 
                        and the slight rocking motion built up to become a swinging 
                        movement which reminded me of the movement of an aircraft 
                        coming in for a landing on a crosswind. There was a change 
                        of position and the object was not totally upright but 
                        rather listing about 20-30 degrees to one side.
                      Suddenly, 
                        there was a few flashes of multicolor lights from the 
                        top of the object and a faint bluish-greenish glow showed 
                        from the bottom part and the object started to float away 
                        quietly towards the south gaining altitude slowly at first 
                        and then increasingly fast. When the object started to 
                        move I felt some vibration and heard a faint, low pitch 
                        humming sound.
                      After 
                        another multicolor light display the object climbed straight 
                        up very fast and still silently. It changed direction 
                        several times in a series of sharp, right angle turns 
                        and then disappeared. While I was close to the object 
                        there was a faint smell of ionization, not unlike that 
                        smell present in high power radio station transmitting 
                        rooms, when they used vacuum tubes and there was also 
                        a taste of metal in my mouth. The cars and trucks started 
                        leaving after the object flew away and we climbed in the 
                        car and drove on until we reached a truck stop restaurant 
                        further down the road were several other witnesses who 
                        had stopped for coffee. Our driver, who had stayed inside 
                        the car, told me that there was a lot of static in the 
                        car's radio while the object was nearby.
                      Some 
                        people at the restaurant told us that sightings are common 
                        in that area. I also remembered that in 1972 I was flying 
                        near the same area one night and an airliner ahead of 
                        my airplane reported a U.F.O. I did not see the object 
                        myself but listened to the radio conversation between 
                        the airliner, the air traffic controllers and other airplanes 
                        on the area. There was a U.S. military aircraft in the 
                        area that night in 1972 and after landing I talked to 
                        the crew which had seen the object. The subject never 
                        came up again after that night. In 30 years of flying 
                        and being a control tower operator for some time, I heard 
                        many UFO stories but had never actually seen one until 
                        that night in Brazil in 1994. Upon my return to the U.S. 
                        some weeks later, I filed Reports of this sighting to 
                        every possible government agency but never received any 
                        reply.
                      The 
                        next day after arriving in the city of Sao Paulo I was 
                        at the airport and after identifying myself as a visiting 
                        airline pilot I reported the sighting to the Brazilian 
                        aviation authorities who listened to the report and took 
                        some notes. I made a couple of sketches of what the object 
                        looked like and its apparent path of flight in the area 
                        of the sighting.
