Hi!
A couple of weeks ago I heard this 'squeaky' sound as it went dark - almost like a child's toy. You can briefly see it on the video, but it is quite some distance away and it only gives an indication of speed and sweeping motion. Location is a field in Yorkshire, close to a small lake.
I'd be very interested in know what it is! If anyone can share any opinions I'd be very grateful.
Thanks for your time.
EDIT: Have added in YouTube link as video doesn't seem to be processing here: https://youtu.be/SAsCacB0ZKI
