Myself and wife saw a ufo whilst staying at Oasis Village, Corralejo, Fuerteventura in 2018. It was at 11:30 at night, whilst we were sitting on our loungers after dinner as our room was so hot as had no air con, and we were looking up above the palm trees at the sky. This oval-shaped flying object just went past from left to right. The only way you could tell that the shape was oval at night, was because it had a line of red light going around the outside of the oval, and it also had a line of green light flashing outside of the red line. It was silent, estimated 50-70 feet long, about 2000 foot up. When it went behind the palm trees to the right, I stood up to get a better view but lost sight of it, but my wife saw it from where she was and said it did what looked like a 90-degree turn towards to mountains or sea.
