When I was working at BHL, I got quite friendly with Al Savard, a Sikorsky rep. he told me about the Los Angelis Airways S61 that had the first blade failure. His bosses told him to get down there and just calm thinks down a bit. He had this unenviable job as the boss of the airlines favourite grandson had been flying the aircraft.
He also said that after many requests to update the 61 with more powerful engine, and composite blades, they were quite happy to do it, but they wanted the operators to put up some money up front, but nobody would.
