Looking on the map, the green patch to the North of the airport is the only uninhabited area. I suppose the pilots must treat that as a safe zone, also it's very beautiful over the estuary. However there is the A27 between it and the airfield.
Pilot originates from the north green zone crosses the A27 but does not wait until he is properly over the airfield and begins ascending.
As he descends he is east and slightly south of the A27 heading W, and steers port perhaps to land on the A27, until with a few metres left the aircraft flattens and rolls right, perhaps ground effect.
