Last week there were lots of these, or something very much like them, flying over.
First they went one way and then they came back again.
Sometimes 1 or 2 or even 3 at once. They are very loud and I could hear them coming from a long way away but each time I was doing something and couldn't rush out to take a photo. So this picture is from pixabay free images.
It was all to do with joint maneuvers between two air bases in Norfolk and Suffolk.
I think they use this - which is a few miles from us- to navigate by, especially at night when it is lit up. We could see the top lights from the smallholding 30+ miles away - Suffolk is pretty flat!
I'm very fond of helicopters.
When the National Grid Helicopter, checking the High Voltage power line, flew over the smallholding I used to rush out and wave.!
In Ipswich we often saw the Police helicopter - I didn't wave to that one!
