Hi folks,
Hope this isn't old news. Mentioned before (at http://www.secretprojects.co.uk/forum/index.php/topic,703.0/all.html) but not (I think) illustrated herein so far is this 'Submersible Flying Boat' from Joseph Ardo, (U.S. Patent Reference 1421369, patented 4th July 1922).
Also attached below is an image of the Felix Longobardi 'Combination Vehicle' patent (ref. 1286679) from 1918. (Mentioned before at: http://www.secretprojects.co.uk/forum/index.php/topic,11934.0/highlight,longobardi.html)
