It was August 3 of 2008 at 14:08, I was at my aunt's house at about 10 miles from the volcano, i was staring at the volcano to see the panorama, then i noticewd something strange going up and down, side to side, even hid behid the volcano, since i believe in aliens and UFO's i thought it was a UFO, and i think it wasn't my first sighting, so i got excited and tried to take evidence from it, I tried to photograph it with my phone but the zoom was too little so i went looking for my aunts camera but she had hid the batteries and i couldn't find them, i was afraid it would leave; it took me about 10 minutes to find the batteries and i went to the window but i couldn't see it until, in a suprise had hidden behind the mountain and i took 12 images and 2 videos with her Samsung s630 and for my suprise it had stayed for about 3 hours i think, since i dont think it was there from the beginning, in the proximity of the volcano, i just told my mother and my cousin about this and i dont know who else saw it; i always have believed in UFO's and had a lot of experiences but this one i have proof, I don't know if there were any planes or helicopter there but i dont think any helicopter or plane can rise at that much speed and steer so sharply or even have that shape, since also i play flight simulators and know the planes movements and aerodinamycs. I was thankful that it lasted so long, but i don't know how much it lasted, it kept going after i stopped the photos and the videos and i lost sight when i came back to my house and downloaded the photos, i came to my aunt's house on the night and it wasn't there, the camera's time is wrong.
