I could write a certification standard that every seat would be able to jettision and have its own flotation, emergency air, epirb, satcom link and voice activated systems with internet with dvd player safety systems for land sea mountian dessert survial.
Or better yet a certification standard that it must run on something other than fossil fuels or petroleum products.
So show me the crash data where a fatal S76 crash would have been less fatal with the fuel somewhere else and at what price in operation cost. Just what I thought.
I am sure we will have all those things while you pay $6-7 dollars a gallon car gas in the US
