Cruising by air and sea: brief history, status and outlook for a submersible aircraft

Abstract. Even in a post-modern era, some possible new configurations for aircrafts and spacecrafts remain to be explored. Normally, the main attention was given detaching from ground and by looking at the sky, but the sea should not be forgotten and thus the possibility to go from/to the sky to/from the sea should have to be considered. This paper is just centered around the historical first developments for the submersible aircraft and the possible future developments. Market segments for manned aircraft seems to be largely unexplored.
