Greenknight - orange/dayglo is very easy to see land to land or air to land but air to air and in most weather and lighting conditions I believe black is the best option - it gives a nice clear silhouette and contrasts well with most cloud/sky/terrain.
Al-bert - nice job
it seems that all that is required is 15 mins grappling (drums) a month to be as good as RN SAR (secondary duty) crews
