Howard Hughes owned an S-43. Remember the scene in the movie The Aviator, in which Howard (Leonardo DiCaprio) and Katherine Hepburn fly over the Hollywood Hills, whispering sweet nothings to each other while "Moonglow" plays softly in the background? It was a CGI S-38 in the movie, but it was supposed to represent his S-43. But with those R-1690s and prop tips just inches from the cabin roof, I doubt it would have been as quiet as the movie depicted. Kermit Weeks owns Hughes' S-43 now, and has it at his Fantasy of Flight Museum in Florida.
