Those who know little about helicopters can actually believe that the number of blades is a measure of fitness. Those who know something about helicopters are not so easily fooled.
Those who make 5 bladed helicopters sucker those who know little about helicopters by telling them fairey tales about the number of blades.
Either that, or all you poor sods who fly 4, 3 or even (gasp!) 2 bladed helicopters should run from them immediately!
So far, the problem with the S-92 is getting them to the customers fast enough, it is out-selling the 225 by about ten to one.
Regarding Norwegian SAR, the mission is brutal, 400 NM radius of action, all weather, with large pick-up capability. It is at the edge of the EH-101 and S-92, and probably beyond all other smaller helos. Frankly, it is close to the USAF CSAR in payload/range/hover requirements.
