i think i saw a ufo, the sceen in which the event took place is in my balcony, in my appartment, in middle central america, my appartment is located on the eastern sea side of the counrty i live in now (have been here since 1995).Getting bak to it, i was talking on my cellular phone with my girlfriend, while smoking a marlboro ciggarette, looking up at the bright sky filled with stars, i focused on one particular red/orange color star, thought something was not right about the star, i saw it headding closser to the city and my appartmnt when all of a sudden it took off in the south-east direction makeing a thin wistle sound as if it were a dog wistle but with a high trebble sound, what i thought at the time "i thought i saw one star fall upward or a neibougher throw a fire-cracker", looked left and right on my bakcony and there was no body on their balcony now if im not mistaken a falling star goes down toward the sea as if you are looking up to down.The "star" was a perfectly diamond shape, from the distance of my eye-sight, i measuered it to be at least 4cm big looking uo in the sky, and ass it toko off upward and leav a thin yellow lind behind it, i couldnt take a pic. on my mobile phone because it wasnt enough resolution on it to fucus that far or any stars in the sky.this is my expierence, we are not aloone in this world, i thnk they come down to recon the area for what could be an attack, or they are life form bassed with the same living needs as us humans.
