As i was driving noticed a perfect sphere that seemed out of place flying over a dig site. i attempted to keep an eye on it until i could pull over to take video footage. i did not manage to capture footage at a low altitude as the craft ascended at speed towards a plane flying above. i did not entirely trust what i had witnessed so when i got the chance i started to film the area, i did not think i had captured any evidence until i played back my video footage and have a craft flying past so fast it almost looks like a flash of light until you slow the video down. this is the second time i have seen this craft.
