My wife was returning from an evening out and she spotted the sphere and informed me when she arrived home. about 20 minutes later w ite decided to go see if it was still there. it was hovering above a farmhouse about a quarter of a mile form home…Around a sharp left hand bend. as i drove round the bend and my headlights came in line with the sphere, i flashed my main beam at it. immediately, high up on my right, something flashed 2 beams at my car and illuminated it brightly, scaring my wife. at this point the sphere started to drift slowly in the direction of luton and disappeared over a low hill. i can only assume that whatever flashed its lights at me was in some way guarding the sphere…Maybe a mother ship…Although nothing was visible. the sphere was about 15 feet in diameter and glowing a steady bright orange…Like a miniature sun. it was not an aircraft or a balloon…Neither can hover. i have no explanation for this incident and would be interested in the opinion of other people.
