As you can see from the date in the image, this was a few weeks ago and I have just got around to finding the screenshot. I heard the sound of a larger than normal heli overhead, so checked it out. I found it was an RAF training heli and it had quite an interesting flight. Through Heathrow, sight seeing in the London heli-lane, overhead Hever Castle, along the Gatwick centreline and then onto the coast to see the sea. All very nice and I'm only a little bit envious!
I was wondering, would this be typical of a military training exercise or maybe the heli is being used to give a dignitory a scenic adventure across the South?
