S92PAX - I suspect you are not a pilot OR you have never experienced the rate of closure and late acquisition of small targets like birds and drones and how little time it leaves the pilot to either react or even fully visualise what the object is. I would suggest that Nigel has been around long enough to know it would not have been a bird leaving only the possibility of a mechanical object ie drone. Sorry for my rebuttal by your post seems a bit silly unless of course you are one of those dreaded Drone Pilots!
