USS McCain collision ultimately caused by UI confusion
Alan Cooper observes in his book Inmates are Running the Asylum than the majority of non-terrorist related airline disasters are caused by bad UI.<p>Not instrumentation as such, but the modern version of it which is the "interface."<p>One example he cites is a pilot selecting a destination beacon using a "simple" drop down menu. 2 possible options, similar in name and adjacent on the alphabetized list are deadly in difference. One is the correct orientation, the other takes the plane directly into the side of a mountain.<p>Given the state of confusion that is modern UI design, this revelation is not too surprising.
