Police helicopters are obviously a very useful tool but can be quite worrying sometimes.
A few years ago, where I live in rural Somerset, we had a police helicofter flying around one night at fairly low level shining its search light around the fields and buildings, including my sheds and stables.
Obviously looking for someone, but was it an armed robber or other un desirable, who might break into our house? ( I don't think my wife slept much that night)
It turned out, our local retired vicar had gone out with his dog, and the dog had come home alone.
The unfortunate chap was found dead the following morning.
