I was in my garden when i looked up and saw a plane with trails passing overhead. i decided to take a photo of it to out on instagram. once i took the photo i went inside the house and opened instagram to upload the picture. however when i looked at the photo there was a strange object above the plane. i zoomed in and it looked even stranger - a ufo. underneath the plane there is also a darker object which appears to be a bird. i believe the ufo must be pretty big as it is quite clear and a lot bigger than the plane or bird even at the height it is at. within a minute of taking the photo i went back outside, i could still see the trails of the place but the object could not be seen with the naked eye.
