We were doing a patrol during the night,me and my friend were on guard duty in a military camp wich was a big field in the middle of a big forest.Since was cold me and my friend went into the driving cabin of a military truck so we could see all over the camp without moving and so we could be warm.We heard a quite loud and vibrating mechanical noise and then in front of our eyes we saw it....floating just above the 10meters trees from left to right....we went silent...i said to my friend "do u see what i see????" He answered "yes".Since nobody would have believed us we did nt mention it to anyone.The ufo was of a saucer shape with rectangular windows on the side/s as the side of a passenger plane with the lights on in the inside....and it went floating away...great!((NUFORC Note: Date of sighting is approximate. PD))
