I took this picture of the island of Fuerta Ventura while on holiday on the island of Lanzarote in June 2004.When I took the picture, I noticed nothing out of the ordinary. It was later in the day, when I was looking back through the pictures, that I noticed a strange shape moving across the sky in the picture of Fuerta Ventura.
I uploaded the image onto a computer in the hotel and on closer inspection realized that the strange shape must have been a UFO, though I hadn’t noticed anything at the time I took the picture.
