| Dave Paulley, elsiemw=rtconnect.net, 05.07.2012 In the May 1999 issue of Airpower magazine, page 50 a photo is shown of a S-40 loading at Oakland,CA for a flight to Honolulu. These aircraft were flown mainly in the Caribbean so this seems to me to be a special flight. Does anyone have info on the flight or flights to and from Hawaii like dates etc: Would appreciate any help. Thanks, Dave Paulley | | John Britton, jn_britton=yahoo.com, 09.06.2012 There is a book out, Pan Am and it's planes (R.E.G. Davies), that gives illustrations; that is, if you can find it. It was available on Amazon a couple of years ago. If memory serves, Clippers of that era were bare aluminum, aluminum dope on fabric controls, black bottom, balck or dk blue anti-glare, and international orange recognition on the top of the wing. Same for S-42 and M-130. My father flew all 3. Photo above looks llike dark leading edges, but that is probably shadow. | | CHUCK SAVA, CHUCKRAZ= HOTMAIL .COMit would appear, 06.05.2012 it would appear that not all of the s-40s were amphibian. is this true as i cannot see any wheels on one of them. Secondly. since I am building a model of one I would like to know where or how to find out the color scheme used on the first machine especially on the upper surface of the wing, | | wanshan, 20.06.2011 what type of engine used in the aircraft.pls explain about engine specification | | , soccershoes=gmail.com, 20.06.2011 Sikorsky S-40 | | Roy Lindberg, RoyLindy=aol.com, 19.06.2011 As the note above says the engines in this aircraft were Pratt & Whitney Hornet B , 575 HP.
