Danny - yes, it was a lethal combination. We were instructed to fly all our "rover" patrols at 20 feet above sea level to keep below enemy RDF. For safety I was usually up to 50 feet and even that felt dangerous at times. We did lose planes and crews; can't say how many but I do remember a seasoned pair, Johnny Hay and Eric Warral, who disappeared in an instant when their plane touched the sea.
