It was about when I was 14 years old aprox. I was traveling to Lima to Caraz-Anchas department. It was around 11 p.m. I dont remember exactly.I was looking for the window (whenever I travel at night I like to see the sky), when I saw something like a star, at the begining I dont care about it, but then It changed form a white light color to red then range and yellow and that way very fast... It seemed to be flying over the mountains like if it was following something, but what? I maked me that question... for a while I thought I was following the bus, the I noticed It didn,t. I saw it for about 18 minutes or a little more... then it elevates to the sky very fast and desapeared...
