It was sometimes called &quot;The Explorer&#39;s Air Yacht&quot; and was Sikorsky&#39;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. It was equipped with two Pratt &amp; Whitney R-985 Wasp Junior&nbsp; nine-cylinder air-cooled radial aircraft engines. Over 39,000 of these engines were built, and many are still in service today.</p> <p>&nbsp;</p>http://www.flightglobal.com/airspace/groups/i_love_radial_engines/media/p/77089.aspxFri, 22 Oct 2010 23:31:16 GMT633cdc99-ba90-4fab-88e4-2ee78cef1809:77089flyvertosset<p>Here seen on a Twin&nbsp;Beech.
