One big object the size of four hectars and two other objects the size of four passenger buses put side by side.I did not have the courage to tell anybody about this and I was looking for the proper authority to whom I will relate everything that me and my friend saw that night. Me and my friend watched a wedding dance party that night and were walking in a dusty road about 1/2 kilometer from our house and when we reached the perimeter of the elementary school I heared a high frequency noise like the hissing sound of a blank cassette tape and I thought it was the stereo player they used to play music in the wedding party but it was already far from where we were. My friend looked back at me and asked me if I heared the noise. We looked around but there was nothing but darkness all around because there were no lighting posts in that place. Then I heared a very low frequency sound but not loud. I stopped walking and I looked around once again but saw nothing. We were already in front of the metal gate of the school when suddenly I looked upwards on my left side as the sounds came from and there, I saw a very big object which was moving or flying very slow and very low. The object was round in front and pointed at the rear (as it moved forward on its round part). It was not revolving and it moved in a straight path. I saw that there were lights, some bright red and some were like phosphorescent lights like the ones emmitted by the numbers of a watch. The lights were like those of a valve in a valvestate amplifier and they were not blinking. We stopped and sat on the dust trying to hide in the hollow-block wall while watching the object moved slowly towards the western part. Then when it was on top of us I saw the rear lower portion openned and two smaller flying objects came out of the openning and the 2 objects flew very fast towards the eastern part and the two flying objects emmitted a light blue color. When the two smaller objects returned they were flying very low and theyu were almost touching the leaves of the sugar canes and they stopped afloat in the middle of the plantation right in front of the school. It was very clear to see the objects even it was very dark. They measure more or less like four passenger buses placed side by side and thay did not make any sound. One of the objects protruded something like a mechanical arm and it reached for the dusty dry soil and seemed to bury itself in the ground. We hurriedly jumped to the other side of the wall and peeped through the holes of the designed cement blocks of the wall. I saw the mechanical arm uprooted some sugar canes and brought it inside an openning. Then the two objects flew towards the big thing and entered into the openning. The big object moved in a vertical path higher then it stopped afloat. The lights went out and it did not move while remaining afloat in the air. The form and details of the big object became clearer as it moved upwards. Then it started moving sideways towards the north still in a very slow phase by that time it was soundless. The light turned on and grew bighter and brighter until it was very painful for my eyes to look straight into the object then suddenly it flew in an unbelievable speed toward the west and disappeared. The following day me and my friend went back to the sugar cane plantation to see the place where some were uprooted but in our surprise there were no holes or diggings in the site.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information.
