Clear Costa Blanca sightingA Spanish couple were walking their dog along the pavement. I was walking my dog on the field. I heard the woman say look (mirror)they carried on. I looked up and saw a triangle shaped craft that was phasing (it was as if it was trying to cloak)the craft had 8 small grey blue lights underneath that were blured. It was traveling on a North - South trajectory from Alicante - Guardamar del Segura, Costa Blanca. Heading towards Gibralter. Speed I would estimate at 2000 - 3000 There was NO sound from the craft.
