I saw this at 10.15am uk time over kirton,lincs uk. i was stood at my back door having a cigarette when i noticed an object in the sky. it was moving slowly, almost hovering, then after a few seconds it shot away at high speed in the direction in was coming from. i posted it on the local raf spotters site to find out more. i was told there was nothing flying at that time, the my post was removed and i was told my their admin that is was and f35. the picture has not been edited or photoshopped. not the highest quality as taken from a poor quality phone. your thoughts plz
