Purple Sea

We've managed a lovely walk on the heath after dinner the last three evenings.  The first evening we saw a hot air balloon and the past two nights a family have been flying a large battery powered plane which has swooped over head as we walk.  Its very quiet so not a problem.  We think the people flying it have headsets on which enable them to see the view from a camera on the front of the plane - and what a view it must be across the heath and the woodlands towards the sea.
