I question the thinking that put a single Start/Gen on the aircraft. It would seem plain old commonsense would have dictated such a single point failure as common as a Generator failing would been thought through and a backup source of Electrical Power would have been installed....say like a Ram Air Turbine?
For an aircraft that is so dependent upon electrical power and designed for a Thirty Hour fuel endurance....having an equal amount of electrical power endurance would have made sense.
Or as usual....am I missing something?
