Right so similar thing happened to me back in 2019, field about half a mile from my house in Somerset. Dead silent, no aircraft noise whatsoever, and it just sat there for what felt like ages before moving off at a speed that made no sense for anything conventional.
What I always ask people to consider first - what was the light quality like? Solid white, pulsing, coloured? And did it move at all or genuinely just hover without any drift? Drones will drift slightly even in calm air, helicopters have a distinct sound you can usually feel more than hear. If it was completely stationary and silent thats actually quite unusual.
Also what time roughly and did you notice any animals reacting? My dog went absolutely mental before I even saw the thing, which I've always found interesting.
Would love to hear more detail on this one.
