All the above is valid and thanks for the replies. I was simply trying to ascertain if it was a regular exercise, working with Surrey police. This is considered a low crime area and NPAS is an expensive deployment, I assume only to be used "in extremis". It would be interesting to ask Surrey police via FOI the number of calls at night in this area and the severity of crime involved. Does "miscreant" from a house burglary warrant a helicopter?
Re the CV, it's correct but I am also speaking as a local resident and tax payer, Air Cadet CI, pro aviation/NPAS, supporter of EGKR hard runway etc.
