Boeing spokesmen declined to elaborate on which sensor inputs are used to provide the data in the tanker design
Did they tell the pilots?
This one statement shows what is wrong right now at Boeing. You can unintentionally kill more people with an airplane than almost any other technological device. Playing "need to know" games so that you can sell products into applications for which they may not be perfectly suited is unacceptable when so many lives are at stake. What possible harm comes from telling the journalist what they want to know? If the military system also relies on a single sensor, we should know that even if it is uncomfortable for Boeing. "We screwed up and we are going to fix it" is a perfectly acceptable engineering response to a problem, even if you get punished in the short term by the stock market.
