The UK onshore rotary commercial world is really quite small. Many of us with commercial licences have been around long enough to recognise each other on the radio, let alone by sight on the ground. I have known SND for almost twenty years and his credentials are beyond doubt. At some of the busy main events previously mentioned it seems that no-one recognises certain individuals who, by the way they fly appear to be rank amateurs yet by the way they inter-react with their passengers, are undoubtedly being paid to fly them. If they only ever appear on that occasion, doubts are understandably raised. Without fail, the CAA used to send an Ops Inspector to carry out ramp checks at such events. I no longer attend them due to the nature of my present employment so I don’t know if this still occurs. If not, it certainly should occur.
