The following year Spanish engineer Juan de la Cierva took off and landed on seaplane carrier Dédalo with his autogyro C 30P.

The lagoon at Gardner looked sufficiently deep and certainly large enough so that a seaplane or even an airboat could have landed or takenoff in any direction with little if any difficulty.

In 1919, the American NC 4 became the first seaplane to cross the Atlantic (though it made a couple of landings on islands and the sea along the way, and taxied several hundred miles).

Included amongst the Norwegian aircraft that reached the British Isles were four German made Heinkel He 115 seaplane bombers, six of which were bought before the war and two more were captured from the Germans during the Norwegian Campaign.
