| Description | On the day in question, the witness, a professional drone operator and wildlife cameraman, was working as a volunteer on an archaeological dig of a Roman Villa in Gloucestershire. Around lunchtime, the witness noticed a white object moving in a straight line above the A46, initially mistaking it for a balloon or plastic bag. Upon closer observation, it was seen to be a perfect white sphere, moving erratically for a few seconds before resuming its course and disappearing over a hedge. The object displayed advanced capabilities by coming to a dead stop directly above the dig trenches. |

| Additional Info | The witness spotted the white object at a range of about 1 km above the A46 moving towards his position in a dead straight line. Having flown drones at the site to document the archaeology, the witness was familiar with the air traffic corridor for nearby Bristol airport. Initially thought to be a balloon or plastic bag, it was soon identified as a perfect white sphere, which suddenly came to a dead stop directly above the open dig trenches, moved erratically for a few seconds, and then resumed its course, disappearing over a hedge within 20 seconds. |
