I also heard a helicopter approaching and identified it as an Airbus Juno HT1.
A further internet search revealed RAF Shawbury, which isn’t that far away from where I fished, uses them as a training helicopter.
I find it interesting when you can add meat to the bones, so to speak, in this way.
Fishing, birdwatching and now plane spotting.
Where’s the best place to go for trains?
