https://en.wikipedia.org/wiki/Sikorsky_S-38
The Sikorsky S-38 was an American twin-engined eight-seat sesquiplane amphibious
aircraft. It was sometimes called "The Explorer's Air Yacht" and was Sikorsky's
first widely produced amphibious flying boat which in addition to serving
successfully for Pan American Airways and the U.S. Army, also had numerous
private owners who received notoriety for their exploits.
The S-38 was developed from the Sikorsky S-34 and S-36. The S-38 first flew on
May 25, 1928. The United States Navy ordered two aircraft (designated XPS-2) and
Pan American Airways was an early customer.
A total of 101 aircraft were built, manufactured originally by the Sikorsky
Manufacturing Corporation of Long Island, New York, and by the Sikorsky Aviation
Corporation in Bridgeport, Connecticut. Sikorsky was acquired by United Aircraft
and Transport Corporation in mid-production.

Reproductions
Curtis Johnson Jr., the son of Herbert Fisk Johnson, to recreate his fathers
flight, which he completed in 1998. As of August 2017 the plane is suspended
from the ceiling of Fortaleza Hall in the S. C. Johnson & Son company
headquarters in Racine, Wisconsin . The other S-38 replica, N28V, appeared in
the movie The Aviator (2004), a story loosely based on the life of Howard
Hughes, who owned an S-38 during his lifetime. As of August 2017 it is owned by
Kermit Weeks and located at the Fantasy of Flight Museum in Polk City, Florida,
bearing the Osa's Ark paint scheme.
